Would like to restore the PET to it's original shape if possible so I thought I'd ask if there are original parts before building or buying adapters.

My 013 ROM is broken, tested them with my Willem programmer after building an adapter on breadboard, all came out fine except the 013 that glitches somewhere on every read.

Also need at least one 6550 RAM, haven't found a good 100% sure way to test these yet so it's uncertain if the rest is OK. Thinking of building a RAM tester with a PIC-processor or something...

Coincidence is I just ordered some pcb's to build the 6502 ram/rom board. First one was finished last week.
I'm guessing you know enough about these, interested then pm me.
