Hello everyone, You may remember a few months ago i mentioned this project to do one day and that day has come. The machine is not working but i am working on that (ie recapped, replaced voltage regulator and checked clock etc), anyway my main confusion is with the MPU1 as i may or may not have some components missing. I am not sure if it came from manufacturing like it or they have been removed (from the back it looks like the former and the front maybe the latter. My plea for help is could someone have a look at their board and tell me the values for D1,D2,R1,R2,R3,R4,C1 and T1, i may or may not fit them, i need to trace them out properly to see where they fall in the circuit but it does seem strange. I would be forever gratefull if someone could have a look. I have attached photos so you can see what i mean. (missing components in the red box) Cheers Jim
