Science of Cambridge MK14 (If you thought the ZX81 was bad you should try
this!)
I replaced mine about a week after I built the kit - *easily* the worst
I've ever used!
There were 2 versions. The original one was a sheet of conductive rubber,
and was totally unusable. Sinclair then sold (\pounds 2.00 IIRC) a kit of
metal doems, buttones and plastic sheets to make a calculator style
keyboard, which was little better.
However, the PCB was drilled for a keyboard switch that Maplin sold, and
that's what I fitted to my machine....
There was also a set of edge fingers in front of the reset button that
were for conencting an external keyboard. I believe some people used that...
