My first computer was also a ZX81, then Dragon 32, shortly followed by a 64 with OS9, Basic 09 and Pascal. Then an Amiga 500. PC's after that.
The first work machine I used was an ABS MX Mini computer from ABS Computers in Portslade, Sussex. Wyse terminals and leased lines between five sites, four having two terminals and the main site having four (I think). The language used was Cobol ish, called Simple 7E.
Then a Burroughs B900, and that's when we got the first IBM XT's. Coding was DBase (dunno how many versions) then Clipper, Delphi, C#...
