On Nov 7, 7:00pm in "Mysterious fault....", frodders warbled: ] I also mentioned that I had checked everything; ASIC, RAM, ] surrounding logic, THE WORKS. My only theory was that it could be ] that one or more instrucions inside the Z80B was corrupted. So ] (after 4 months of nagging) I got a replacement (I was a bit ] surprised here as it came together with my copy of Format and ] absolutely free of charge) the other day, and yesterday, I finally ] found the time to solder on a socket and try it out. ] ] AND...it worked! Horray! ] ] Has anyone got any ideas how a defect Z80 could come out from ] production, or how it could have been corrupted on board?
Had you tried resoldering the z80? It's quite likely that it was just a circuit placement fault, and your soldering a decent socket on it might have done the trick. Have you tried putting the old z80 back in your sam?
