> Emulation is cheap but completely unrepresentative of the original experience.
Never enough, but THANK GOODNESS for emulation!
My favorite old skool computer is the IBM 704 that LISP originally ran on. This machine didn't have a visual display or anything fancy. It was the sort of thing where you'd hand in your punch cards and an operator would run your job, then give you back the program results in your mailbox or something.
When I was doing research for writing my blog posts about LISP about a year ago, it was so helpful that a turnkey SIMH environment for this machine existed, that let me run the original software and then get definite concrete answers about its behavior. There were things I was curious about, particularly its handling of the T atom (and whether that remaps to TRUE which is the true truth) that I wouldn't have been able to talk about, had the emulator not been available.
