Remember the ominous core dumps??? Anyhow, I much prefered the analog computers: with a couple of resistors and capacitors one could get results which would have taken (at the time) a few weeks of programming... and for simulations there were no artifacts generated by the digital to analog converter... Anyhow we are getting a bit far from X...
