Hi guys,
I was able to locate a 93 W Indiana jones machine, it's been stored more than 15 years and needs lots of work, it was missing the CPU and dmd driver, yesterday I found a couple of boards, one of them a CPU from 94 like new but it seems some incompatibility, there's a strange chip, rom or pic, is there any way to re write or do something else to get this 94 CPU work with my machine??
Rottendog and TwoBits have after-market WPC89 MPU boards available. Homepin also just started manufacturing their board again.
Quoted from rygar:It is a WPC-S CPU board and it is not compatible with IJ. The empty socket below the game eprom hosts a security chip.
Incorrect. That is an early production WPC-S CPU, and the socket below the game ROM is for a 2nd game ROM, which was never implemented. Specifically, from a WCS 94. Early production WCS 94 games had 2 game ROM sockets. I'm not sure if the Demo Man games that had WPC-S MPUs (very limited #s, have only actually heard of *1* in existence, which was in Ted Estes office at WMS when developing the PIC system - but may be more!) had 1 ROM socket or 2.
The PIC is below the ASIC. It's the 28 pin socketed IC below the crystal.

Someone else found another one...they posted a thread on it a few months back.

I think that may be the machine that was in Ted's office, I discussed it with Ted briefly before the post was even made here, as I sold Dan the ROMs that wouldn't work in his security CPU.
