Larry, do you mind posting or DM the ZIP file with the instructions for replacing the 3 ROMS with TMS-2532 & TMS-2564? Thanks JimI have a ZIP file on replacing the three ROM's with Texas Instrument EPROMS (TMS-2532 & TMS-2564).
It's easy enough just to use the EPROMS. (I may have had to use one PULLUP resistor, I'd have to look
at my Model 1. (Won't be able to do that until Early April.) No need to just use two EPROMS and do a
lot of rewiring.
Do you have the Lowercase modification in your Model 1? What is the number of your Character Generator IC?
