What do suggest for improvement?

There are circumstances where the first byte of the ROM is overriden.
I got a report, where this happens when CP/M is booted.
I myself experience it every now and then.

A simple solution would be to have a jumper that allows or forbids writing to the EEPROM from the apple.

thank you very much

This is a great suggestion. I'll make up a new board design soon.

Until then, here is a workaround that regularly fixes the first byte automatically:
