the acorn electron was a cut down cheaper version of the 6502 based BBC (I had one at home)|. your age group is more likely to have used the A3000 at high school which is an ARM based machine but had many similarities to the BBC and could run BBC BASIC on RISCOS.

that would make sense for infant/junior school level – at my junior school there was a single BBC micro that only used cassette tapes

my high school was well equipped ; it had 12 BBC micros + 4 master 128s and Econet server + hard drive; I will get round eventually to writing the whole saga about the RAT but it will be long and I’ve got to remember stuff from 30 years ago

the A3000 was a powerful machine but would actually have been a bit dated by the time you were in high school. Todays Raspbery PI is 6-10 times more powerful- you can run RISCOS on it and I did give it a try but had forgotten the path structure. its all reversed compared to todays computers; I couldn’t work out how to get networking active or link to Linux/Windows systems – alas, it was now a bit too much for an older chaps brain…
