Somewhat different to me, then: I joined ICL from Uni (so 1900, 2903
[desk-size 1900 emu on 2900 DFC hardware] and 2966 kit) writing PLAN
assembler, macro-generator and COBOL on Georges 1,2,3 and VME/B), worked
for small software houses after ICL, then joined Logica's finance group
where my first boss was Graham Sainsbury (who designed the CHAPS
network), hence financial networks, ATM networks etc.
