    Well, my introduction to computers was not much later. It was 
the Hewlett-Packard small main frame meant to compete with the 
PDP-8 or maybe it was the PDP-11. It rand on Hewlett-Packard 
Basic. It used an ASR-33 as the terminal although I think the one 
in our shop used a KSR-33 with separate tape punch and reader in 
the rack. I taught myself to program it using this machine. It 
had 32 _kb_ of memory. Could be expanded to 64 Kb with a second 
rack. Had flashing lights and toggle switches on the front to 
wake it up and tell it where the tape reader was. -hp- got into 
making them because it wanted something better than the PDP for 
automated measurement systems.
    Teletype machines are really sort of elementary computers, 
converting serial to parallel and then to analog.
    Unfortunately the computer "expert" in our facility was a 
psychopathic bully so I had to learn whatever I knew on my own.
