Zitat von

I marked in Green what I have and in blue what I think I have but would have to check.
I wish you were in the USA then I am sure I could help. But shipping to Europe and back is just not something that I would do nowadays & too expensive.
Perhaps you should spend your next holiday in Spain (with all those chess computers in your luggage) and visit Berger?
Usually, a ROM dump and possibly a PCB photo are sufficient for 'hap'.
If the EPROM is socketed, then such a ROM dump shouldn't be too difficult (provided you have an EPROM reader).
