Looks right up my alley :)

Yeah, the DDI5 is good, if you can get one. I tried a couple of years ago but he wouldn't send to the UK (from Poland).

And the CPU saga continues.

Whilst waiting for the CPUs I ordered, I figured why not swap the Z80 from the original + board to the spares board. Turns out the Z80 from the original board is dead...

So both Zilog Z80A's made in 1984 within 8 weeks of each other, both dead or marginal. That's a bit disappointing.

EDIT: I've swapped CPUs and the original + board works with the spare CPU, but the original +CPU is totally dead. Good job I ordered tow Z80 replacements.

Really, you have no luck with your Speccies...

The 128K +2 works just fine :) as does my Spectrum 48K with rubber keys, it's just this damn Spectrum Plus.

Bad batch of Z80s obviously.

Well, given I'm working on 2 boards, strictly speaking you're not wrong :)

It would seem a possibility. And both on issue 4s boards too.

And both seem to have the M1 issue too.
