Original ROMs are not always easy to obtain however images of the ROMs are readily available, which lead me to design and build an EPROM card, which never has gone beyond the prototype stage maybe I should look into laying out a PCB and having some cards made.

Paul,

are you aware of the PRM-85 project? If there are enough interested parties it might be possible to produce another batch of this board (I would like to have one).

Martin,

Yes I am aware of it, but when I got my 85A there was none available and there was no indication that there would ever be more so I struck out on my own and created my own design, but I have never produced a PCB for it, it only exists as a hand wired prototype. If there was enough interest perhaps I could lay out a PCB and have one produced. I have a good stock of the CPLD that I used on it and could provide levels of kits from board with programmed CPLD up to fully assembled.

Paul.
