The repairs of my #Enterprise64 continue. It can run an old 32K ROM but not a newer 64K ROM. Also it fails the RAM test. Replaced the old soldered RAM chips with new socketed ones. Same result. Main suspect now is one or more of the address lines on the PCB. Unsure how to test it, as one of the ASICs does some clever memory banking, which probably means they're not directly attached to the #z80 CPU.
I'm way out of my comfort zone here, but I'm trying to diagnose and fix a 40 year old #vintagecomputer.
