I can't seem to find the schematics in the database, could anyone help me point out the CPU and address bus resistors? Cheers

You will have to meter them out, likely ones near the CPU and ROM..
Once you worked out it, post it here ;)

That topic is locked ;)
However, I have a troubled board and I know the answer.
Marked them up.
@exxos you can add this to the folder.

No problem. Actually gave me an idea while double checking, I might have 2 address lines not fully connected....
