For sure.

Hopefully it'll help me with getting the original machine working again now I have a known good reference to work from.

I should also be able to verify which of the two identically marked CPUs is the 2nd CPU which has a baked in mask ROM which will help. At least I hope it will!

OK, this is driving me bonkers. The working machine is now doing nothing, not a solitary beep when powered on. It was working first thing


Gaaaaaaaaaaaaaaahhhhhhh!!!!
