Final report on 464 repairs
« on: 08:54, 20 June 17 »
The 464 is now alive and well now that we solved the slow speed tape problem and minus a CLR key.

Parts replaced were:
3 x ram chips
IC110 Z80 CPU
IC108 6845  CRT
Tape drive belt
Tape idler tyre (modified O-ring used)
Tape counter drive belt (rubber band used for the moment).

This needed much less chips than the 6128 I recently did.
The ram was not getting hot either.

I do need either a clr key or a keyboard if anybody has one.

Hi Mark

I have a SPARE  "CLR" Key here.
Do you still want one.

If it Ain't Broke PLEASE Don't Fix it.
