After a break of a couple of years I’ve decided its high time I had another go at repairing my RML-380Z. You can read about this machine and my previous attempts here.

A quick recap…

When I power the machine on I get a a fixed, pseudo random image on the screen but no other signs of life. I’ve re-seated chips in their sockets and swapped the RAM chips around the board but that’s about it.

It has been suggested that I swap matching logic chip to see if that gives any clues…
