My computer history

1. My first ever computer, back in 1979 was an Sinclair MK14 and cost me £39.99 in kit form.
This was nothing more than a programmable calculator with 256 BYTES of RAM.
The buttons were the very first generation of conductive membrane and were absolutely useless!!

First job was to change the keyboard buttons!

I used to do a lot of MK14 programming, so much that would sometimes count in hexadecimal.
