Shnedler Systems TurboMaster Reverse Engineering

Progress:

• PCB scanned
• Artwork converted to EAGLE schematic and PCB
• PCB design ordered
• PCB design populated and confirmed working
• U1 PAL reverse engineered

U4 is not registered, so should be easy to determine. U6 and U18 are registered, so tougher to do.

Does anyone know who might have source for the pa.exe application linked on this page:

The equations it creates from the 27c020 dump from u4 are too large to synthesize into a 16v8, but the dump is too large for Logic Friday, so I am wondering if I can try to modify the source to spit something out that is a truth table that Logic Friday can consume.
