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!
