For Commodore 64 repairs, see Ray Carlsen's repair page at:
http://www.prismnet.com/~bo/commie/repair.html
Your specific problem may not be addressed here, but at the top of the
page, there are e-mail links to Ray. He is very knowledgable and helpful
on Commodore repairs. I consulted him via e-mail once for a broken SX-64
I picked up. He helped me get it working again. You can also get
schematics of the C64 at:

Problem: I just noticed the C64 seems to have
these dead keys '5, 7, 9,
and 0'. Looks to me like a dead bit on the keyboard controller, but I must
confess to ignorance on the internal details of how the C64 accepts key
presses. Can anyone give an overview, and would anyone know of a fix?
