Remember the ominous core dumps???
Anyhow, I much prefered the analog computers: with a couple of resistors and

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...
