Re: what was your first computer and do you still have it?
Not my own but a schools. A LACE MK2A analogue device, 16 valve op amps a valve multiplier unit (which never worked) and a rack of 20x10 turn precision pots,all powered by huge stabilised psu's. All inputs and outputs were brought out to a patch panel so an analogue circuit could be set up. readout was via a crt or the meters on the op amps. If I remember correctly there were a set of buttons for 'initial conditions', 'run', pause', and 'stop' All relay driven
It was built in a gigantic set of 3x19" racks in one 6' high chassis.
