With bootstrap, loader, trigger set,
All needed checkout done,
With core enough and hardware up,
‘Twas time to check Phase One.
The Operator pressed bootload;
Programmers cried, “A toast!”
Just as power failures blacked out
The entire Northeast coast.
This article is old, but interesting nonetheless. A New York Times piece on Tom Van Vleck, the CTSS operating system (predecessor to Multics and Unix), and the possible inception of email at MIT. Has an interactive feature that allows you to send an email on a simulated CTSS terminal and a game, too.
It’s pretty cool that this little-known software engineer and the operating system he helped create are getting some mainstream recognition after a half-decade of obscurity.
