How the NORAD graphics in WarGames were generated is quite fascinating.

The TL;DR; is that they got a consultant who had contacts at HP and managed to borrow a $90,000 (inflation adjusted) 9845C desktop running BASIC and filmed one frame and one colour at a time.

@futurebird
Those new-fangled QWERTY keyboards remind me of a *proper* keyboard (literally so) I saw at the Science Museum in London some years ago. A 'Hughes printing telegraph', apparently - from 1860!

@simontatham Something like this? There are roots of all polynomials with degree up to 18 with coefficients from \( \{-1, 1 + (i - 1)t\} \), where \( t \) varies from \( 0 \) to \( 1 \) and back.

@marklemley @SteveBellovin The smiley is older than that. When I was studying for my ham radio license (1967 or 1968), I commented on it when I saw it on my elmer’s teletype.
