Cassette tape - the flash drives of the 80's
Remember cassette tape? I remember using these tapes to save and restore
programs using a ZX81 when I was fifteen. The procedure was fraught

was all about patience, I wonder if I should add, learnt to program on a
ZX81 to my CV? There was no Internet and the only reference was manuals
and magazines. And then there were the programming language books. In
those days they were not called dummies!!!
