Default Re: Zx81

Just dug out my original 'normal' ZX81, the one which is still in the original casing / keypad, and fired it up only to find that only about 5 of the keys were working, even though it was put away fully working probably not more than 2 years ago.

The problem is the usual, the ribbon connectors have hardened with age and they fell apart into little bits of plastic confetti as soon as I tried to separate the PCB and upper casing. It's like that all the way back to the keyboard entry point on this one so I can't employ the usual dodge of snipping the bad ends off and making new ends a few mm further back. It's a complete goner.

A replacement key membrane is already on order - if anyone else has one of these safely stored and believed working, better check it out while the membranes are still available. They aren't too badly priced, around £14 to £17 including post. Available from a number of sources.
