Early Computers

Dad had his first encounter with a computer in 1961 on a school trip to a local aircraft design office. It was a Ferranti Pegasus. He built an analog computer for a school project in 1963. These are some of the early computers he worked with, or on:
  • Ferranti Argus at Southampton University in 1962.
  • English Electric KDF-9 at Keele University in 1964.
  • AEI 1010 at Associated Electrical Industries in 1965.
  • Elliott 803B at UCNW Bangor in 1966 - About 250 were built. Only three survive, one at the Science Museum , London. There's a simulator for it that is written in Java [Download]
  • Elliott 4130 at UCNW Bangor in 1968.
  • DEC PDP-7, PDP-8 and PDP-9 at Time Sharing Limited in 1969 (also accessed from home via a 100 Baud modem!).
