Re: I'm curious...
Wow - that takes me back. My first real job included writing a bunch of HP-IB drivers (inclduing the base HPIB card driver) for different pieces of test equipment at the old (long since bulldozered) BAe/Sperry Gyroscope factory in Bracknell. It was all quite cool ... to test laser gyro Inertial Navigation Systems.
I seem to remember trying not to kill Michael Hesletine who was defence secretary at the time. For some reason the powers that be decided it was a good idea to seat him on our 3 axis test table and pretend that we were moving him. There were so many ways it could have gone wrong ... large test able to move in multiple directions at high speed. Fairly high power lasers.. all driven by software that was still a bit flakey. For safety, we decided it was better to unplug everything and just lie.
