need help identifying and repairing this old video poker machine...it has a single circuit board with single connector (j1)with pins 1-65, it has a single dip switch with 8 switches, located near  this connector    it uses a zilog Z8400 cpu
has a D8255ac-2 chip with paper label stating new install 6/30/86 ! 
i repaired the wg-4600 monitor, but the wiring harness has been hacked badly(is there a good hack?)  i will need to replace/rebuild the harness
marquee states it was a "skill draw"
probably used in a bar somewhere, has coin inputs, no outputs
besides filling in a landfill, any help would be appreciated restoring this old beast.
thanks,
mike

Can't say much from a description alone -  :211-

here are a couple of picts,  thanks for the help

Mike,

Might I suggest converting your images to jpgs or gifs before uploading them. Those file types can be displayed right in the post on anyone's computer. There are probably a lot of members who don't have Photoshop, and although there are converters/viewers available to look at those images, it still requires that they be downloaded to be accessed.

so correct....first time uploading pictures for me, but i am finally catching on...thanks for the input

Those are much easier for everyone to view.  :89- :71- K+

You might also want to post pictures of the outside and inside of the machine since at this point, no one is even sure of the model/brand. :79-

lol...there's a chip on the top left corner labeled "new" ... in like  1982?  :96-
I wonder what machine this board is from?

That's why I asked him to post more pictures of the machine. :89-

monitor is wg-4600    coin input unit is std-634   original (not used now) power supply has 5773-09474-x2 screened on board
very large isolation transformer    small 24 v ct transformer added for another voltage source
1-65 j1 board header is .156  and the socket consists of 5 individual 13 pin molex connectors placed end to end

Oh My God... :5-
A Hurricane Katrina victim...surely the caps on that regulator board are dried out...
the rectifiers are probably shorted out too...you're asking for big time troubleshooting experience.
These components look like a game from the pits...your pockets better be bottomless too...
If this thing ever comes to life...it'll be like something from  Micheal Jackson's "Thriller".

I don't recognize that machine at all. I imagine it's an amusement-only poker made for one of the southern states. The board with its 7 EPROMs looks like a development of the Lulac design, but there are endless variations on that design. The 3 EPROMs left of the picture will be the game ROMs and the four in the other corner will be pre-built graphic images. The small transistors probably drive the lamps in the buttons, but I don't know what the large ones would drive - solenoids, maybe. Buttons will connect to the group of resistors at top right. The 40 pin chip bottom center is probably an 8275 video generator and the group of six resistors in the middle looks like the video color mixer. The board looks in good shape and is probably functional, if you can work out how to connect it up.

since i am not flush with cash, probably my best bet would be to put the board in a picture frame and hang it on the wall as an example of 1980"s gaming boards

Well,
Not yet...lol
Did you try hooking it all up to see if you get any video?

no video, what i have is 5 -13  pin .156 molex edge connectors that hook to the board header j1 which also has 65 pins...not  all positions in each connector are used, however the position that was the 2nd connector, pins 14-26 has just a bunch of wires hanging there,
no connector a.....lso there are several wires in the harness that appear to be cut, missing,etc...i would probably have to rebuild the complete wiring harness using some kind of wiring diagram...i recapped the wg-4600 and it works great.  no sounds either...
monitor picture tube does show some screen burn from past decades, but can't make much out except perhaps player 1  and player 2
thanks,
mike
