Granted its quirkly 10 bit design and G1 ROM nmakes interfacing EPROMs directly impossible. I have looked low and high for an adapter or schematic and all I found was the T card. 17 logic chips, 4 DIP switches and 8 EPROM is kinda klunky and clumpsy looking not to mention big!
Any of you have detailed schematic of that? with modern technology I could probably shrink that to a single PAL chip and consolidate all EPROMs to 2 chips (or 1 16-bit EPROM)
