I replaced the 74s32 with a 74ls32 (the closest replacement I could get) and the machine didn’t leap beck into life.
Disappointed doesn’t come close.
I walked away for a few days and came back to it and it came up.
I powered it of and on again and it didn’t. That’s a bit odd.
Out came the boards and chips were pressed into sockets. Power up again and Bingo! Off and on and still OK.
So here’s the question… Was it the keyboard adapter that caused it to fail or was it just coincidence? I’m not sure if I dare find out yet.
Hi, thanks for the write up on your 380Z. Since you first wrote this series I guess you have moved sites, as the files for your uploaded COS40B ROMs are no longer there. Can you add them somewhere please? I have the same machine with different issues.
Regards,
John
