I found a superbreakout board used for years as spare, so some chips were missing including roms.
I installed all missing parts and tested the board with the roms from another board. One ram was faulty but it has been an easy fix.
Now I have a working board withoit roms (pcb version with 3 1024x8 roms)
Do you have spare to sell me or any idea how to replace them?
Thank you!

Is it not possible to burn the roms you need? ???

I haven t any idea which kind of rom it is.
Should be 2048x8 but pinout is different from proms i know...
Mostek 28000p is similar but power pins don t match. Seems it needs -12v
I ll check better

During the night I had an idea.
I want to try to transform my -04 board version to a -03 version.
It means to populate the "small" proms instead of the 3 big roms.
Small proms are 74s 573, easier to find (and to burn of course)
