You said that your display was rolling from side to side, like the horiz hold or sync isn't working. In spite of that, can you push the buttons and get it to deal cards, does it accept coins and give credits? If so that means it is booting and running, just has a display problem.
That or the graphics chips. It it coins up and you get the sounds of the deal ... chances are the graphics chips are where you want to start. Your getting the raster on the monitor and I am thinking the RGB is there as well. I dont feel you should adjust the guns on the neck. Get a signal to the monitor and then think about those adjustments. Is your monitor a G07?

Thanks for the advice, but no boot, no sound, nothing audible when using the coin-op. I am pretty certain that SolidSilver has confirmed what I suspected from the get go. Missing EPROM #1, and as SolidSilver pointed out, it is not the correct version for the machine either not to say an older complete set would not work.


I sent him (SolidSilver) a pm to see how much it may cost to get his valid EPROM's burned into new EPROM's for me. If it is financially too expensive or too much hassle I will likely pass, especially with there being no guarantee of it getting the machine up and running. I may have to consider it as a parts machine or list it for sale as is and present the information that we have come up with here as reference for the potential buyer. May convert it into a MAME machine with an old dell laptop that I have here and run the original game.


Without having a valid set of EPROM's, the project is on hold.


For the time being, I put the machine back together and am awaiting a reply.

What type eproms does it use, can you read the ic manufacturer's part number on the back of one, like a 2716 or 2732 or similar?

This guy sells a lot of eproms for a fair price, he even has older ones, but you may have to buy more than you need, so ebay might be a better source. But this will give an idea on cost for the eprom itself. Whoever makes the eproms for you can probably take care of getting the blank chips.

What might be real handy would be to send your mpu board to someone that has a working Cal-Omega machine and see if it works ok.

As you get the manual and eprom software chips straightened out I'd make sure about all the power supply voltages. That is a basic thing that has to be right. If you don't have a meter they are available for less than $10 from places like Lowe's, Home Depot, Harbor Freight, etc. They are fairly easy to use and can help you to eliminate things to wonder about if they are working. When you check the voltages write down what they measure so you can tell the experts here and get advice if they are incorrect.

The fluorescent lights in the machine simply run off the 115 vac that comes in from the line cord and they usually don't require much to repair, just a lamp, starter and ballast. If a machine's fluorescent lights come on that still doesn't mean the power supply is ok because those lamps don't use the lower voltages from the power supply. Things like the circuit boards and pushbutton lamps use the voltages created by the power supply. That information should be in the manual you are getting.

The person where you bought the machine, might they be helpful on parts such as the eprom software or other items? They may have other Cal-Omega machines that they are scrapping out or taking parts out of.


I have a couple good multimeter here that I have been testing with but am awaiting the manual for proper reference. The person that I purchased the machine from does not normally deal with anything solid state and does not have access to any other parts, he primarily works on old school pinballs. Only one of the 50w florescent bulbs work. I tested the other ballast's and they work as well. Have not tested the power output with the multi yet.

If I had the option to do this locally at low to no charge, it would be an excellent option and suggestion. I am hard pressed to spend a bunch of money I do not have for a maybe.


I am considering, not for sure, but maybe trying to erase and re-flash the four eproms that I have here on a diy breadboard system that would need to be configured with a pc. Hummm  :Scratch-Head: ... I have a couple things for alternative but would prefer the original dedicated system if at all possible.

Dormi is the person here that really knows the CEI machines. He repairs the boards, and possiblie could help with software, but I'm not 100% sure if he can. You could try send him a PM stating you have a board to check and that its possiblie missing software. It's worth a shot..

Rick, I emailed you the 903 schematic & block diagram.
Your eproms are likely either 2516 or 2532; mine are the latter.
Either chip is dirt cheap on eBay, new and used. Anywhere from $2 to $5 each.

There's gotta be someone on NLG who can dupe these eproms; hello out there?

SolidSilver .... hope I am not intruding but I have been looking for info on a 904 board. It has the chipset for just the Jacks or better poker. I dont have sound and no paperwork. I need to check my 12 volts if I remember right that is what drives the audio. Is there any chance you have info on that board and any other paperwork associated with it? Also how easy is it to update it to a double up game?
Thanks for your time and efforts.

Jim or anyone else!
I have a couple different version 906 turbo boards. They both work in my CEI that uses the 904 normally. But the basic poker games DO WORK on my machine, although the buttons don't match the screen on some. That's fixable in a way by just changing the stickers on the buttons. 
Do you thing this would work in RPM's machine? It should I think.

I am not educated on these machines at all. This is my first and only cntact I have had since I played them when I drove a tractor trailer in the south back in the mid 1980's
I think he said he has a 903 board. I dont know if the pinout is the same for the 904. If you feel that the turbo board you have will plug and play in a 904 cabinet, I could be interested in it. I also would like to get the sound to work in mine. I guess I will just poke around and check the PS and speaker before I do anything else.

Fatman, the 903 and 904 boards are identical; the only difference is that the 903 had a small game history memory chip, and the 904 has pads for a small piggyback board carrying a much larger memory chip. This expanded memory was a requirement for Nevada gaming machines. The circuit and physical pinout are the same, and they are interchangeable. PM me, and I'll email you a schematic of the 904. I have no docs on the backplane, which is where the fairly simple power supply circuit is located; it's not difficult to trace power on it.

906 board might work, enough to tell you if your problem is on the main game board or not; but it will probably not work correctly: the wiring to the pushbuttons will be different.

Similarly, upgrading to the DoubleUp feature depends on your machine: if you have the older 10-button unit running a 903 or 904 board,
you can't: DoubleUp feature requires an additional row of buttons. If you have a 15-button machine, easy-Peasy; or if you have a much later machine built for 906 or 906 Turbo board, DoubleUp will run with the 10-button panel.

Pics of the machine, and interior, (does it have a payout hopper?) and boards, would help us identify what you have, and perhaps provide more help.

Model # in CEI CO1cr and it does have a payout hopper, unlike the double ups in the truck stops in SC.

Greatly appreciated! I have been busy with other things for the past couple of days but I have briefly reviewed the schematics. I'll post an update over the next few days if I have made any further progress.

And in the meantime, I'm going through my old dusty drawers, and those of some friends, looking for other CalOmega chips.
Might be a week or so, but we'll see. If successful, I cannot believe a full chip set, even if we need to buy new blanks, would cost
you more than $50.

Shorty, the answer is absolutely, positively.....maybe  :Scratch-Head:

It may be that a complete set of virtually any early software would bring the machine to life, enough to tell him what else, if, needs fixing; but it would not likely operate properly on his physical unit. I'd really like to get him software that would actually work in his machine.

He has an arcade machine with the 12-button panel; it requires arcade DoubleUp draw poker software to work properly.
I'm not all that familiar with the early arcade machines and, comparing his machine manufactured date with the gaming software I'm familiar with, it would seem his machine originally had a DoubleUp capability earlier than the gaming version.

I'm working on it with another friendly NLG'er, but let me ask you: can you burn...
     1. Those old 2532 chips, which require special burn voltages?
     2. From a software file, as opposed to copying a chip set?

If the answer to both is YES, there may be 2 NLG'ers  I can involve.

And as our numbers grow, we will rule the world!  >:D   Bwaaaa-ha-ha-ha-ha!!!

(Oops, gotta back off on that Porto...)

Is there a difference in the game chips from the smaller up right casino machines and the larger arcade style cabinets? I have the smaller game size. It has a 904 board. I don't remember what the EPROM stickers said? It's out in the garage waiting for repairs. It has a monitor chassis problem. My screens all washed out, but I card see the cards. The board must have a problem because my middle button won't hold the card. It was like that in a different cabinet I use to have too, no middle button.

Two things determine which chipsets will work in which machines.

1. the Game Board. Virtually all the old machines use 903/904. A very few, like Keno machines, use the rare 905 board.

2. The machine's button layout. The standard poker layout is 10 buttons. Double-Up machines,  have 12 (arcade) or 14 (gaming)buttons, as Double-Up requires 4 special buttons: Take, Double, High, Low. But then, there are some with 15 or 8..... :Scratch-Head:

Well, DANG!!!  I just saw a screenshot on a website that has nothing to do with us NLG'ers.
It's an alleged screenshot of the 7.6 game arcade game, showing the DoubleUp option!!!
Pic attached.

RPM, you may just be in luck, and I may just be able to add some serious new info about CalOmega software.

Working on a way now  to get you a complete set of clean 7.6 eproms.
