Re: Spectrum 128K toastrack jail bars?

Then replace C28 with a 47uF capacitor (original is 22uF, right of the 5 way keyboard connector) Replace caps C7 and C8 with 1uF ceramic capacitors (next to IC12 and IC13 RAM chips, bottom left of the board). You could also add 1uF caps underneath the...

Re: New to repairing ZX's

Your second one has a quite early ULA at 8106. Nice. As most of the chips are socketed you could try swapping them around and may get a working zeddy. Thanks, but I'd rather repair them both.
