If you have a slot machine or you have bought one old used vintage slot machine and want to have some fixes to get it work then obviously you will think you need a machine technician. Many of you will even think of taking it to some repair station to get things done. But here in the guide you will find some of the repairs that you yourself can do with your slot machine and you need not need to join machine technical repair training school.

Like any other machines Slot machines too are a blend of electronic and mechanical components, that wear with age and require routine repairs. Before you begin to repair yourself do note that every slot machine that you have purchased whether old or new comes with installation and user guide manual. You need to read that many a times until you are familiar with each components and parts of the slot machine and understand thoroughly as how the slot machine works.

In your guide to repair slot machines you will find some common repairs that can be carried out by you, some videos to watch as well. If your slot machine has some complex issue then obviously you require a qualified technician.

Changing the Top Florescent Light

The top florescent light bulb is easily changed by following these simple procedures. The replacement bulb is an F15T8/CW 18″ 15 Watt bulb which is available at most hardware and department stores or may be purchased online at Ebay or Amazon or realslotmachinesforsale under the category ‘parts of slot machine’.

  • Open the main slot machine door and ensure the door is fully open. Turn off the power to the slot machine. The power switch can be found with the main door open about midway down on the right side just inside the machine.
  • If the machine is equipped with a top ticket printer, you must pull the bottom of the printer out far enough to see where the ticket paper is located, and note the area large enough to place a couple of your left fingers under.
  • Remove the top metal trim strip which is a cover plate to the right of the ticket printer and/or is located along the bottom of the top glass. There are a couple of clips on the back of the metal trim strip that fit into notches on metal bracket which holds the top glass. The metal trim strip should be lifted upwards and outwards to remove.
  • Once the metal trim strip is removed, the next step is to remove the top glass. Note that some top metal trim strips have a slot in the top that holds the top glass and they must be removed very carefully as to not damage or drop the top glass.
  • You can now see the top glass is held in place by usually two or three clips that rise above the metal bracket behind the top metal trim strip. Now slowly lift up on the top glass from both bottom edges until the top glass until it is high enough to gently pull it forward and allowing it to slide down and away from the top track and clips holding it in place.
  • Once the top glass has been removed, put it somewhere where it will not get knocked over or broken. You will see the florescent bulb in the middle of the top box area of the machine. Care should be taken removing the bulb as it may be very hot. Remove the old bulb by twisting the florescent tube about a quarter to half turn allowing the two prongs on the bulb to slide out of the fixture on both sides of the bulb.
  • Remove and discard the old bulb. To install the new bulb, align the two prongs on each side of the florescent tube with the slits on each fixture in the top box of the slot machine. Twist the bulb into place normally using about a quarter to half of a turn. If the bulb is not secure or aligned, repeat the procedure.
  • If your slot machine is an IGT S Plus machine, it is equipped with a florescent bulb starter. Then you can replace the starter when replacing the florescent light bulb. The starter is an FS-U Universal Starter. They are available at most hardware and department stores or may be ordered online too. The starter for the top florescent bulb on an IGT S Plus machine is located directly behind the florescent bulb fixture on the left side of the slot machine in the top box area.
  • It is replaced by twisting about a quarter to half a turn as it is held in place with a bayonet type mount. Remove the old starter and discard. Replace with a new FS-U Universal Starter by aligning the two pins on the bottom of the starter with the notches in the starter receptacle, pushing it up into the starter socket, and then twisting it a quarter to half a turn into place.
  • Prior to re-installing the top glass, turn the power switch on the right inside of the machine on to verify the bulb works properly. If it does not, turn the power off and check that the bulb is properly installed and secure. If replacing a starter, check that it is also properly installed and secure.
  • After verifying the bulb is working, it is now time to replace the top glass. If your slot machine has a top ticket printer, ensure the ticket printer is still pulled out so you can place your fingers in the opening while replacing the top glass.
  • Carefully and slowly lift up the top glass placing each hand under the bottom of the top glass. Slide it into the upper edge track on the top box of the slot machine carefully lifting it so it slides into the tracks while being able to push the top glass back far enough to clear the two or three raised clips on the metal bracket where the top glass holding track is located.
  • Gently and slowly lower the top glass behind the clips so as to allow them to hold the glass in place. If properly secured, the top glass will not be able to slide down or out of its position. Keep a secure hold on the top glass until you are certain it is secured in the proper position.
  • Replace the top metal trim strip by aligning the two or three hooks the back through the metal bracket that supports and holds the top glass. Once the hooks on the back are in place, gently push the top metal trim strip down and it should snap into place. If you have a slot machine with a top ticket printer, close it tight into position. Close the main slot machine door and you are ready to play.

Changing the Belly Glass Florescent Light

The belly glass florescent light bulb is easily changed by following these simple procedures. The replacement bulb is an F15T8/CW 18″ 15 Watt bulb which is available at most hardware and department stores or may be bought online as spare parts of slot machine.

  • Open the main slot machine door. Turn off the power to the slot machine. The power switch can be found with the main door open about midway down on the right side just inside the machine.
  • Facing the slot machine door, look on the right side of the door just around from bill acceptor area. You will see a knob sticking out that is approximately the size of the end of a regular pencil. This knob when pulled out releases the slot machine belly glass assembly (belly door) to fold down so the bulb can be accessed.
  • There are a couple of very important thing to remember prior to pulling this knob to release the belly door. First try pulling gently on the knob. If it does not allow you to pull out and you have a lock installed directly above it, the lock must unlocked in order to allow the release knob to pull out. When pulling out the release knob, be ready for the belly door to fold down.
  • Most of the time you must lightly pull on both sides of the belly door to get it to fold down, however always place your hand under it so it does not fall down too quickly causing the belly glass to break or crack.
  • Once the belly door is in the down position, you will see the access to the florescent bulb bracket that is held in place by a small Phillips screw. Remove the screw and place it the coin tray so it will be handy when you need it after replacing the bulb.
  • The long metal bracket that holds the florescent bulb must be slid slightly right or left so as to be able to lift it out of the belly door. Gently lift the metal bracket with florescent bulb out of the assembly far to be able to turn it over to replace the bulb. Be cautious as the bulb could still be hot!
  • Grasp the metal bracket holding the florescent bulb and remove the old bulb by twisting the florescent tube about a quarter to half turn allowing the two prongs on the bulb to slide out of the fixture on both sides of the bulb.
  • Remove and discard the old bulb.To install the new bulb, align the two prongs on each side of the florescent tube with the slits on each fixture that is on each side of the new bulb. Twist the bulb into place normally using about a quarter to half of a turn. If the bulb is not secure or aligned, repeat the procedure.
  • Now turn the metal bracket that holds the newly installed bulb over and back into position in the belly glass assembly. Slid the bracket slightly right or left into position and replace the small screw which holds the metal bracket in place.
  • If your slot machine is an IGT S Plus machine, it is equipped with a florescent bulb starter. So you need to replace the starter a well when replacing the florescent light bulb. The starter is an FS-U Universal Starter. They are available online and you can purchase one.
  • The starter for the belly glass florescent bulb is located on the back of the main slot machine door on the lower right hand corner as you face the back of the door.
  • It is replaced by twisting about a quarter to half a turn as it is held in place with a bayonet type mount. Remove the old starter and discard. Replace with a new FS-U Universal Starter by aligned the two notches on the bottom of the starter, pushing it into the starter socket, and then twisting it a quarter to half a turn into place.
  • Prior to closing the belly glass door, turn the power switch on the right inside of the machine on to verify the bulb works properly. If it does not, turn the power off and check that the bulb is properly installed and secure. Also check to ensure the starter is properly installed and secured.
  • Lift the belly glass assembly up and push it into place in the slot machine door. Ensure the belly glass door snaps into place and the knob on the side of the door is in its normal position. It is spring loaded so as to not allow the belly glass assembly to open unless it pulled. If the belly door appears to be in place, pull on both sides of the belly door to make sure it is locked and secure.
  • If you unlocked the lock above the knob, re-lock it. Close the main slot machine door and you are ready to use your slot machine.

Changing the Push Button Bulbs

All of the slot machine’s push button lights such Play Max Credits, Spin Reels, Bet One Credit, etc. are easily replaced by following this simple procedure. The replacement bulbs are #161 on IGT S2000 machines and #555 on IGT S+ machines and may be purchased from online stores.

  • Fully open the slot machine door. Look on the backside of the door. Each push button will extend down from the shelf on the door and will have a small wire bundle going to it. Identify which push button bulb needs to be replaced.
  • Carefully pull down on the bottom of the push button area that is normally white and is where you will see wiring connected. Using your thumb and two fingers, pull straight down and the bottom portion of the push button should snap out.
Wms Slot Machine 250 Troubleshooting
  • You will now be able to see the bulb in the top area of the lower push button assembly. Use caution as the bulb may be very hot. Pull the wedge bulb out and discard it. Notice the slot in which the bulb located.
  • Place a new bulb in the slot noting the direction of slot ensuring the new wedge bulb is inserted so as to line up in the slot. Push the new bulb into place.
  • Replace the bottom of the push button assembly by inserting it into the top portion of the push button assembly. The bottom portion will snap into position. Ensure that none of the wire connections have been accidentally knocked loose on the bottom of the push button. Note the push button light will not illuminate until the slot machine door is closed. Close the main slot machine door and you are ready to play.

Changing the Small Panel Lights

The small panel lights that illuminate the denomination amount and other areas behind the glass are easily changed. For denomination amount lights on the IGT S2000, a #73 bulb is needed and a #86 bulb is needed on the IGT S+ slot machines. They may be bought online from slot machine selling sites.

Here it is described as how to change the lights behind denomination amounts such as .25 Cents. Other small panel light bulbs are changed in the same manner.

  • Fully open the slot machine door. Look on the backside of the door. Note the location where the denomination amount would be located near the center just below the slot machine’s center glass. The area will appear to be flat with a small bulb holder projecting out that is slightly larger in diameter than a regular pencil and is flat on two or four sides.
  • This bulb holder is removed by simply twisting it a quarter to half a turn and then gently pulling it out of its socket. It is held in place by somewhat of a bayonet type mount.
  • Once the bulb holder is removed, pull the wedge bulb out of the socket and discard the old bulb. Caution should be taken as the old bulb may be very hot. Replace the bulb by firmly inserting a new bulb into the socket of the bulb holder being careful to align the wedge bulb correctly into the slot.
  • Take the bulb holder and look for two notches on each side of the opening where the bulb holder is inserted. Note there are two notches on the bulb holder. Align the notches inserting the bulb holder into the panel.
  • Gently twist the bulb holder about a quarter to half a turn to lock it into place. Verify the bulb is illuminating, and if not repeat the procedure using a different new bulb. Now close the main slot machine door and ready to use.

Cleaning Your Slot Machine

This is common thing and all you need is usually nothing more than a damp cloth to clean the exterior cabinet of your slot machine. Never use any abrasive or ammonia based cleaners on the cabinet of the machine.

The slot machine top, center and belly glasses may all be cleaned on the outside by using a window cleaner. However if you own a slot machine with a frosted exterior glass or one that has any exterior decorated markings such as stars, a window cleaner should not be used as the cleaner may damage the exterior images. Care should be taken cleaning interior glass as a cleaner and cloth may damage labels or markings.

The inside of the slot machine should not require cleaning other than occasionally removing dust. This can normally be done with a damp clean cloth, however ensure the power switch has been turned off prior to cleaning.

When wiping dust inside your machine, be careful not to loosen any wires or connections. Do not use a damp cloth on the face of your reel strips as the playing symbols on the reel strips could come off or become torn. Also be very careful not to touch the back side of your reel strips with a damp cloth especially if the back sides of the reel strips are black. This can cause damage to this type reel strip.

When your Slot Machine Doesn’t Power On

When you get a slot machine and wish to locate or set up at your place, determine the household 120V AC outlet you are planning to use has power. Keep in mind some outlets are controlled on and off by a wall switch.

  • With the slot machine unplugged from the outlet and surge protector, open the slot machine main door. Remove the coin tray by lifting up and pulling out the tray. Simply pull it out and down to remove the tray.
  • The hopper is on the bottom floor of the machine and slides out on two base rails along two metal guides. Slide the hopper out slowly by grasping the handle with your left hand and supporting the hopper with your right hand. Do not use the black hopper bowl to pull the hopper out of the slot machine.
  • On the lower right corner of the slot machine you should see the black power cord coming into the machine. The power cord plugs into the Power Distribution Unit which is located on the back wall of the slot machine.
  • Verify the power cord is firmly plugged into place into the right side of the Power Distribution Unit.
  • Place the hopper back into the slot machine making sure it slides in easily and completely with the base rails on hopper guides on the bottom of the machine. The hopper plugs into a receptacle toward the back of the machine. It is designed to fit in easily without using excessive force.
  • The coin tray can be easily put back into place by ensuring the alignment pins on the coin tray match up to the top alignment holes on the bottom side of the machine. The tray should be pushed down into place. Make sure the tray is even when pushed into place. If the coin tray is not aligned and even, remove the coin tray, and repeat the procedure.
  • Verify the power cord is firmly plugged into a good surge protector. Plug the end of surge protector into the outlet you have verified is good, and make sure the on/off switch on the surge protector is turned on.
  • Now turn the power switch on the inside right of the slot machine to the on position and verify the slot machine is powered on by lights illuminating.

Jackpot Payout Reset

When your slot machine just hit a 25,000 credit Jackpot it now needs to be reset to continue playing. Depending on the model slot machine you have and the amount of the payout will determine the best course of action.

If you have an IGT S+ Slot Machine and your win is under the maximum payout amount specified on the center glass of the machine, the hopper may run out of coins or tokens. This is normally displayed by Error Code 3300. In this case it usually a simple matter of taking the coins or tokens that have been paid out and putting them back in the hopper allowing it to fully pay out. However, if you won a large jackpot that is “hand pay out”, then follow the steps below.

  • First open the main slot machine door. Locate the Jackpot Key which is normally kept inside the slot machine in a plastic envelope on the side of the cash box. If you do not find it inside the machine, often times the Jackpot Key will be strapped with the main slot machine door key. It is a small key as pictured below.
  • Take the key in hand and locate the jackpot reset which is a keyhole located on the right side of the slot machine. It is normally about two-thirds up from the bottom of the machine.
  • Insert the Jackpot Reset Key into the keyhole. Turn the key only one quarter turn to the right. This will reset the machine, and once you close the main slot machine door, you will be ready to resume play.
  • Note that if you turn the Jackpot reset key multiple times you may place your slot machine into a test mode and will thus delay your ability to continue playing.

Some of the Error Codes you get on Slot Machine

Error Code 3300 (IGT S+ Machines)

Simply put Error Code 3300 is normally telling you your hopper is low on or completely out of coins or tokens.

Open the main slot machine door. Look into the hopper. If it is empty or has just a few coins or tokens, place about 500 coins or tokens back into the hopper. Close the main slot machine door. In a few moments you should hear the sound of the hopper’s motor turning and soon the remaining coin payout will begin.

Error Code 3100 (IGT S+ Machines)

Error Code 3100 (Extra Coin Out Tilt) normally signifies either a jammed/stuck coin or token in the coin-out chute on the hopper, or the hopper coin-out sensor has detected the hopper may have paid out an extra coin.

  • Open the main slot machine door. Remove the coin tray by lifting up and pulling out the tray. Simply pull it out and down to remove the tray.
  • The hopper is on the bottom floor of the machine and slides out on two base rails along two metal guides. Slide the hopper out slowly by grasping the handle with your left hand and supporting the hopper with your right hand. Do not use the black hopper bowl to pull the hopper out of the slot machine.
  • Inspect the hopper to determine if any coins/tokens appear to stuck or jammed in the hopper knife or the hopper coin-out channel.
  • If a coin appears to be stuck or jammed, empty the hopper of coins/tokens for easier access to clearing the jammed coin/token.
  • Once the stuck or jammed coin has been removed, place the hopper back into the slot machine making sure it slides in easily and completely with the base rails on hopper guides on the bottom of the machine. The hopper plugs into a receptacle toward the back of the machine. It is designed to fit in easily without using excessive force
  • Refill the hopper with the proper size coins or tokens. The coin tray can be easily put back into place by ensuring the alignment pins on the coin tray match up to the top alignment holes on the bottom side of the machine. The tray should be pushed down into place. Make sure the tray is even when pushed into place. If the coin tray is not aligned and even, remove the coin tray, and repeat the procedure.
  • Close the main slot machine door. The error code should be gone and the machine is ready to play.

Error Code 12 (IGT S+ Machines)

The 3.6 volt battery on the slot machine CPU Board normally lasts for years. However when an Error Code 12 is displayed, this is an indication the battery voltage has dropped below 2.9 volts and is now a low battery.

It is recommended to replace the battery as soon as possible. They can be purchased online from ebay, amazon or realslotmachinesforsale. When ordering a replacement battery, they will provide you with detailed instructions on how to change this battery which is located on the slot machine’s CPU Board.

In order to reset Error Code 12 temporarily, simply open and close the main slot machine door. It is important not to wait for a long time to replace the battery as data stored on the RAM may be lost. Replace the battery Asap.

Following are some of the other error codes that might interest you to solve your problem in repairing the slot machine

Hopper is Full and Coins Go Down a Chute to Bottom of Machine

Slot machines that accept coins were designed this way because when used constantly on the casino floor, hoppers could quickly fill. There is a coin level probe on side of the hopper that looks like a brass screw sticking inward toward the hopper bowl. This probe detects when coins/tokens are at a selected level, and will cause the subsequent coins/tokens played to go down a chute to the bottom of the slot machine.

Provided your slot machine sets on a regular casino slot machine stand with holes in the top and the holes are aligned with the slot machine, those coins which bypassed the hopper will go down the chute, through the hole in the bottom of the machine, through the hole in the top of the stand, and into the open area in the stand cabinet. As casinos have done for years, place a small plastic tub in the slot machine stand cabinet to collect these excess coins.

Retrieving Currency from the Cash Box

Though not all slot machines are equipped to accept currency in order to comply with certain laws but if your slot machine is equipped with a bill acceptor, bill transport and cash box, the bills in the cash box can easily be retrieved.

  • Open the slot machine main door. The cash box door is located just under the yellow chute for the bill acceptor. Ensure the cash box door is fully open.
  • On the right side of the cash box toward the top is a release level. Push release lever down and pull the cash box straight out toward you. If the cash box seems difficult or impossible to pull out, make sure you have pushed the release lever down.
  • Hold the cash box in both hands and turn it upside down. Notice on the bottom of the cash box is a door which has two small finger sized holes on one side. Normally the door is held closed by a small piece of electrical tape so the bottom cash box door doesn’t come open while removing it from the cash box chassis of the slot machine.
  • While holding the cash box with the bottom door up toward you, open the door and you will see where the bills are stored. The large spring expands as more and more bills are added to the cash box. Remove the bills by pulling them straight out.
  • Close the bottom door of the cash box and re-secure the door using the same small piece of electrical tape. Turn the cash box around to the original position when you removed it from the slot machine.
  • Align the flat top of the cash box with the flat surface at the top of the cash box chassis from which you removed it. Slide it firmly into place. Now close the cash box door and the main slot machine door and you are ready to use it for gaming.

Sigma uv1700 Video Slot Machines
1999-2005

[email protected]

Introduction.
First I would like to state that in regards Sigma slot machines, no one seems to be archiving any informationon these. It really too bad as these are *great* slot machines forthe home. Excellent graphics and game play with good bonus games.And they are fairly inexpensive compared to Williams and IGT models,yet have all the same features (if not more).

Sigma was bought by Mikohn around 2003, and then was sold toMultimedia Gamingin 2005, where the UV1700 was shelved. So most Sigma uv1700 video slots were made between 1999 and 2003.Because of the Mikohn buy, the uv1700 history is a bit hard to track,hence this web page. Though most pinball people hate slotmachines, I find them interesting (especially given their reasonable price.)I mean compare a Sigma uv1700 video slot to the industry leader (at the time),the Williams 550 video slot. They are very similar, maybe the Sigma is evensuperior (better animation, easier to work on). But the Sigma is 1/4 the price of a Williams 550 slot machine.For 'bang per buck' the Sigma UV1700 is hard to beat.

The Sigma 1700 slots are generally pre-TITO machines (TITO is 'ticket in, ticket out'). Meaning they take coins and paper money, and have a hopper to payout coins. Unfortunately Sigma was the innovator of coin-less slots, and this showed upin the trail end Sigma uv1700 slot machines (TITO with ticket printer and no hopper). Generally speaking, most new slotsafter 2003 are TITO and don't handle coins, only paper money and tickets.So it makes sense that some of the newer Sigma 1700 models didn't have hoppers. The first coinless slot machines to be installed in a major casino was theSigma Derby horse racing machine. But to me TITO machines are not a good home slot machine, and is not really the type of slot I would want in my home gameroom.(Though do I really want to 'cash out' 800 credits in nickels at home?Heck no, but maybe it's just the idea that I could do that.)

Sigma Gaming Brief History.
Sigma Gaming was actually founded in Tokyo (Japan) back in 1984. They were the first non-U.S. slot makerto gain Nevada Gaming Commision certification. They did relocate to Las Vegas in 1996, but the Japanese touch remained. Sigma was known for technical innovations,and Sigma aggressively marketed their slot machines and poker machines. This spurred competition, and IGT (International Gaming Technologies)decided to take Sigma to court over copyrights.(Sound familiar? See the Williams slot history fordetails.) In 1989, IGT claimed the Japanese Sigma Gaming had been stealing patented game designs from IGT. This was eventually settled out of court.Sigma is one of only a few manufacturers to hold an unrestricted license to use the Telnaes technology (which IGT holds the patent) that allows for virtual reels and unlimited odds. (Spinning reel only, does not applyto video slots, see Williams slots for moreinfo on this.) The Telnaes technology enables Sigma to offer the ability to provide high-end payouts and progressive jackpots without limitations.

In 1990 Sigma came out with the first 'slot top' (sit down) slot machines.Though not a good home slot machine format due to size, these were very popular inthe casinos (and still are today). Players loved the comfort of sittingdown to play. In 1991 they were honored with the State of Nevada Governor's Industry Appreciation Award for its continued contribution to Nevada's growth. Again in 1996 Sigma received the award again.

Sigma was also the first company to embed a dollar bill validator into their slot machines, which made playing a Sigma slot one-stop shopping. To the casinos it was not about comfort, butto keep players at one machine for a longer period of time. There would be no breaks to go sit down, and no need to run to the cash machine. The ideas worked, and soon IGT was copying Sigma Games.Sigma wanted to build slot machines which were user-friendly. They made their slots easy to use and more comfortable to play, hoping this would lead to player loyalty.

Sigma also released the firstred, white & blue-themed game (Patriot), and a patented locking cashbox extractor. The cashbox extractor featured a design licensed to and utilized by two other leading slot machine manufacturers (Bally and Wms), and was offered by JCM.

Sigma Gaming made other slot play innovations too. Though they didn't invent it, early on they were part of the trend to increase the playusing big credit bonuses. If you payed the full price to play (all the creditsthe game would except for one spin, which in some cases was up to 50 credits), the bonus structure made it worth your while. This is standard nowadays.

Around 1999 Sigma jumped on the video slot machine bandwagon with theSigma uv1700 video slot. The video slot was a marketlargely developed by Williams (Wms), and one that Wms excelled. Sigma met andI would say surpassed Wms with the uv1700. Animation is more refined onthe Sigma, and the machines are far easier to repair.

As for repairs, Sigma slots were easier for casinos to repair (and us too, since these are now in our homes!)For example the UV1700 Sigma slot machines shown on this page arebased on 300 mHz Cyrix/Pentium PC computer hardware, using standard 168 pin 256meg SDRam DIMM pc100 or pc133memory sticks and CD ROM drives. But the PC board isa bit different than those seen in your home computer.Instead of a board with a zillion connectors, the Sigma 1700 slot uses a DPX-80 board from Densitron Technologies andGamingboads.com, using a single 'ConnectBus'connector. This board eliminates the need to plug and unplug different connectors for power, HDD, FDD, monitor, etc. That is, all power, I/O, and interface signals are routed to a single ConnectBus connector. This makes the board literially 'plug and play', allowing Casinosto easily swap a motherboard to fix a machine. Everything is on one board,so it's pretty painless. (Though a hardware 'clear' is still requiredthough to change a game.)

Unfortunately this all came to an end in 2005, as Sigma (called Mikohn since 2003) was bought by Progressive Gaming International (PGI). At that time PGI stoppedselling the Simga UV1700, andnothing further has come of the Sigma 1700 platform.

The guts of a Sigma 1700. Looks like a regular PC eh?
That's because it pretty much is a regular PC.

Sigma uv1700 and uv1900 (sit-down) Slot Machine Hardware.
The motherboard used in Sigma 1700 slots was a 'ConnectBus' Densitron Technologies DPX-80 board,with a single connector for all power and hardware. This allowed a techto replace a motherboard in about 10 seconds.The processor is a Cyrix MII-333GP (333mHz clock speed with a 83mHz bus 3.0x, 2.9 volts.)Memory includes two SIMM 72pin EDO sockets (not used) and one DIMM socket (SDRam 168 pin 256megpc-100 or pc-133, depending on how old the DPX-80 motherboard may be.)Interestingly many games can run with 64meg or 128meg of RAM (thoughKiss requires the full 384meg, Garfield runs at 288meg or above.)The Densitron Technologies DPX-80 board supports up to 450mHz clock speed using a socket-7 compliant processor.Design features include PCI accelerated Fast Ethernet LAN controller, PCI 64-bit accelerated LCD/CRT graphics controller with digital LVDS/PaneLink interface, PCI Ultra DMA/33 EIDE controller, expansion for PCI/ISA buses, analog video input port, touchscreen controller capable, DiskOnChip flash disk socket to 144 Mbytes, 16-bit stereo sound system, two USB, two parallel, four serial, MIDI, mouse, keyboard, and two floppy disk ports.

The Densitron Technologies DPX-80 as used in the Sigma 1700.
Shown is the board loaded with 256meg of DIMM pc133 RAM.

In 2002 Densitron Technologies introduced the DPX-91 motherboard, which is backwards compatible with their DPX-80 and DPX-81 ConnectBus motherboards.Though I've never seen this used in a Sigma uv1700 slot machine, there is a chance itmay work.

Sigma 1700 17' Touch Screen.
The really cool thing about the Sigma uv1700 is the 17' color touch screen.Great resolution and graphics, and a touch screen to boot. It's a nicefeature, especially given the price the Sigma 1700 sells at. The touchscreen is nicely implemented into the game play too (some games use itmore than others.)

The coin door opened on a Sigma 1700. A pretty tight design!

Sigma RAM.
All Sigma uv1700 games have a single DIMM ram socket,usually fitted with PC133 256meg 168 pin SDram. This is the maximumRAM size that will fit in this socket (though some older games may onlyhave a 128meg SDRam card.) I have found some uv1700 boardsthat want PC100 SDram, and won't boot with PC133 (or vice versa.) Either the game will lock up at boot (no power-on 'beep'), orit will beep on and off constantly (signifying a RAM issue.) Reseatingthe SDRam or replacing usually fixes this problem.Note that Garfield requires pc133 DIMM RAM withSerial Presence Detect (SPD) aka Low Density. This is denoted by a second notch cut into the ram on the sides (the second notch is abovethe stock notch seen on 'regular' RAM.)

There are also twoSIMM 72 pin EDO RAM sockets, which will hold 64meg each, andthat are not utilized. Only games I am aware of which require more than 256meg of RAM isKiss and Garfield. These games require the DIMM 256meg SDramplus the two SIMM sockets to have 64meg each, for a totalof 384meg (actually Garfield will run at 320meg, but Kiss requiresthe full 384meg.) Also some brands of PC133 DIMM memory won'taddress the additional SIMM sockets - The DIMM memory must haveSerial Presence Detect (SPD). So in the case of Garfield and Kissyou must have the 'right' 256meg DIMM SDram memory with SPD, in addition to the twoEDO 64meg 72 pin SIMM memories.

Finally you can run most Sigma games with just the two EDO SIMM memories installed (128meg), andno DIMM memory. So if you can't get a board to boot right with the DIMM SDram,sometimes trying the SIMM memory can get a board working.

Sigma 1700 Parts and Repair.
Of all the slot machines I've worked on (and I've worked ona bunch!), the Sigma 1700 is probably the easiest to repair.It's more like a PC computer than a slot machine. There'sjust one board (the 'motherboard'), which is basically a PCmotherboard. I've yet to need to repair a power supply.The mother board uses PC-100 or PC-133 stick 256meg memory (available at the localcomputer store), and a standard CD or DVD drive to read the CDs.The CDs themselves are copyable with say Nero, which means backupsare a breeze (and I do suggest you keep a backup around.)Memory is kept intact with two standard drug store coin batteries(CR4025).

The only thing I don't like about this platform is thetime it takes for the game to boot. Because it's a PC based system,it goes through a memory test at power up (which can be abortedif a keyboard is attached), and the time it takes to check the CD rom.The game reads the entire CD rom and does a checksum against the valuestored in the motherboard's PLCC u52 game chip. If these don't match the gameaborts. This was done so someone doesn't 'hack' the CD rom (easy to do!),changing the game code. So total boot time is probablya minute or three, where most other slot machines boot in 10-20 seconds.

Coin and Dollar Bill Validators.
The coin hardware (if the Sigma has it, not all do) can utilizestwo different coin entry systems.An IDX coin comparitor (programmed for the appropriate coin) canbe used, assuming it has the correct 'personality plug'. Also aMicro Comparitor MC-40 (cmi# 66460089) can also be used (12vdc,InHhi,PR7).In either case both of these systems have the coin-in optics built intothe comparitor.

Micro Comparitor label showing the proper part number.
This is important as there are many different models of Micro Comparitors.

The bill valiator used is JCM's WBA-13 model, which is a reallynice dollar bill acceptor system. If using version 3.75 of the software(it has a 4meg 274001 EPROM built into the WBA transport), it willaccept all colored U.S. money with no problems. Note the head is thesame on a WBA12 and WBA13, but the transport is different.

Sigma 1700 Game Software.
Software (game changes) for a Sigma uv1700 is pretty easy too. There is a single smallPLCC (square) 32 pin 4meg game EPROM chip on the DPX-80 board at U52. And this chip must have a matching game CD ROM. A Dallas 'All Clear' chip is run first at U51 (replacing theboard's 'boot' chip), clearing the memory.Then the boot chip (u51) is replaced, and with the newPLCC game chip (U52) and game CD ROM are installed, the game should run.Upon bootup, the CD ROM is fully read and its checksum compared to the checksumstore on the PLCC game chip (u52). If the checksums don't match, the game gives an error and does not proceed.

Interestingly the 4meg PLCC game chip is pretty much blank.It only contains the checksum of its matching game CD ROM, and some general game parameters (like whether it's a nickel or quarter game, etc.) About 200 bytes of actual info is on the game PLCC U52 chip, and the rest of the chip is blank with '00' stored at each byte. So the PLCC chip onthe motherboard is really only used to verify the CD ROM (which is whereall the game software resides.) Because state regulators don't want tomake game swaps too easy for casinos, the PLCC chip's stored checksumis used so no one can put a 'hacked' CD ROM in the Sigma.

The PLCC chips (Bios, BdBoot, Game chip) and the two coin batteries.
The socketed 'Disk on Chip' provides a solidstate disc work area for the operating system.

Sigma 1700 Progressive Slots.
Sigma made a couple games that were progressive only. That is,they won't run standalone without a networked computer behind them.This is unfortunate as the two progressive games (Lava and Easy Riches)look like good games. (I can load the games and add credits, but theywon't spin because of the lack of a progressive network to support them.)If anyone knows how to get around this, please contact me.

What's the 'Best' Sigma 1700 Game?
I get asked a lot, 'I want a Sigma slot machine, but which is the best onefor my home?' That's a hard question to answer, as it's like asking, 'which flavorof ice cream do you like the best?' Actually I like all the Sigma 1700 games,but Battleship is my favorite.

Sigma Boot Codes.
There's a two digit LED on the corner of the CPU board.I don't have the error code definitions, but I have managedto write down what a proper uv1700 does upon bootup:

  • c1 c6 c3 - real fast upon initial power on.
  • 06 0d 0e 31 - then game beeps that familar PC boot sound.
  • 31 - stays at this until memory test completes.
  • 3d 6f 42 4e
  • 52 60 62 ff - boot up complete, game should be running, stays at FF.

Sigma Power-On Constant Beeps.
A common boot up error at power on is constant beeping from the speaker,and a C6 error on the LED. This happens when the SDRAM memory stick is bad. Sometimes a simple power off, reseat the memory stick, and power back on will fix this problem. But other times a new memory stick will be required (168 pin 256meg SDRam DIMM pc100 or pc133.) Look at the existing memory stick and see if it is pc100 or pc133 (it should be labeled), and get the correct variety. Using a pc100 memory stick in a board made for pc133 won't work. If the memory stick is unlabeled, best guess is to go with pc133 (which is the most common.)(Yes there are several different versions of the mother board, and the earlierversions use pc100.)

Sigma Game Numbers, Titles, Pictures.
Below is a list of all the Sigma uv1700 video slot machines I have found.The game numbers are important, as the game number on the u52 motherboardchip must match the game number on the CDrom. Note I have some u52 chipsbut no matching CDrom. If you have a cdrom for any of the game numbersI am missing, I would really appreciate hearing from you.
