Spectrum Computing

I was a backer and followed the whole debacle

Wikipedia is pretty much on the nail factually: https://en.wikipedia.org/wiki/ZX_Spectrum_Vega%2B

Thanks, can anyone point me at a PCB layout diagram for the Toastrack 6U?

I was getting an occassional problem with my toastrack displaying black and white vertical bars on boot. This seems to be because the toroid is quite "loose" and looks like it happens if it presses down on the PCB. Mine has bare wires and does not look as if they've been well wound. What's...

Thanks can you point me at those instructions if you have a link?

I have a working rubber key but poorly Spectrum+ but obviously prefer the keyboard. When I tried this only a few keys worked on the + which may mean the membrane needs replacing.

Deep In Brixham I tinker away with my 4 ZX81s, 2 QLs and 2 x Spectrums. Recently acquired a 48k+ which needs nursing back to life.
