Hi at all,
i buyed a new keyboard for my ZX81, the old one sadly the ribbon cable are overheated, and
is brittle and interrupt it the traces. It's very difficult to install a new one?
Need some particular attention to centre the keyboard, or is perfect matched like the original?
Thanks,
Matt

Re: ZX81 install new keyboard
The new keyboard membrane should fit exactly. However, you only get one go because the glue is very, very sticky.
Before removing the backing, and after removing the old keyboard membrane and cleaning off all the old glue, I suggest you do a test fit.

Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb
Looking forward to summer later in the year.

It looks like a good one.
I normally buy replacements from RWAP on Sell My Retro, but his current listing (here) looks to be sold out.
