Quick question, I know it has a different DSR (Data, Sound, ROM) but shares the same main logic board as Qix, is the third board (whatever it does) the same too?

Slither just has two boards: video and D/S/R.

Qix has three because the Data/Sound and ROM/I/O boards are separate.

Hmmmmm... that makes me happy, because that DSR board looks rather reproducible. :)

Is there anyone here whom can get me a high res pic of both sides of that board?

You'd da man! Thanks again!

It all looks pretty straight forward on the schematics, one whole portion of the EPROMs is its own circuit and goes straight to the connector for the video board, the rest I can probably break down into more manageable and easier to debug blocks. My idea is to see if I can hand-wire my own board and get it to work, and if it does then figure out a way to make a PCB out of it hopefully with fewer, more modern components, which shouldn't be all that tough once I've proven the circuit is reproduceable. One thing would be to squeeze all the EPROMs on to one or two larger capacity ones, but this is a big learning curve for me so I don't know if that's automatically possible.
Everything seems to be off-shelf-components and there doesn't appear to be any dreaded PALs or custom chips, the one wild card are the two "jumper plugs", one labeled 26-00002-016 in the pic. I get the impression that they're nothing but, as the name suggests, jumpers perhaps for different board configurations or a very weak attempt to make boot legging more difficult, the schematics don't show what pin jumps where. I hate to ask more favors but if anyone can map them out say with a continuity meter that be of an enormous help.
 
From the manual:

The EPROM Memory in a given game may be implemented as banks of either 2716 or 2732 EPROMS. The EPROM type for the video bank is selected by the decoding jumper (JUMP PLUG 1).

The EPROM type for the Data bank is selected by the decoding jumper (JUMP PLUG 2).
 
can you not burn slither roms and put them on any other arcade pcbs? that is what my repair guy said,So i was going to have him do a slither.
 
well i guess i am going to tell him he is full of shit and put him to the challenge.lol Or just use a qix pcb? I am going to have him make me a scorpion pcb out of a scramble pcb. From what i read its possible.
