Sinclair ZX80 / ZX81 / Z88 Forums

Hi people.
My name is João, I'm 28 years old and I'm a proud (or was) owner of a Sinclair 128k ZX Spectrum +2 UK Grey version dated from 1986.
My +2 was working fine but I change the PSU and i get the polarity inverted. I managed to get it working like power light drive and sound. But no video unfortunetly.

This is my story soo far.

Hello João

Welcome to our forum

All the Sinclair computers are polarity sensitive.

I suggest you post details of the problems you are having in the ZX Spectrum area of the site here
