I did my CS O-Level at the local FE college
Because it had teletype with a line to some OU computer somewhere and the grammar school I went to didn't.
After about a term, someone at the FE college saw the bill for the line and worked out that buying the then new 380Z would be much cheaper.
It had proper 8" discs, not the wimpy 5 1/4" ones in the picture, and by putting one in the wrong way, I broke it...
Ah, happy days. It was fixed in a week or two. I still have good memories of the keyboard - a mechanical one you could really bash.
