Having a clear out of some old books recently turned up the above bookmark given away with 80’s computer magazine Your Computer. The cover of the first edition, which I still have, is shown below featuring the then state of the art Sinclair ZX80, ZX81, BBC Micro and something I can’t identify right now. What’s interesting is what was considered jargon then. So, for example, we have “interface” that includes “A centronics or RS-232 interface [that] allows you to plug in most printers or disc drives”.
My particular favourite though is the advice on “an ordinary cassette recorder” which can be connected to your “micro”. Ah those were the days when you could hear your programs being loaded!
