Looked for the jumpers you wrote on your git, but didn't find them ...
EPROMS
Du kannst ein EPROM-OTP 27c040 verwenden oder ein Flash-EPROM 29LV040.
Bitte achte darauf, dass der jeweilige Jumper JP5 oder JP6 gesetzt wird!
Ansonsten funktioniert das Umschalten der Banks nicht korrekt, da sich das PIN-Layout dieser EPROM-Typen leicht unterscheiden (PIN 1/PIN 32)
Hello, if the floppy does not start correctly when it is switched on, it is usually due to a contact problem with the EPROM or RAM. It can of course also be a ROM problem if it has not been written to correctly. If you send me a PM with your e-mail address, I can send you a ROM image for testing. The jumpers J1-J3 switch the banks.
