Free software was born here,
Stallman was one of the ITS hackers. But, funny enough, Microsoft as well: Bill Gates and Paul Allen wrote
Micro Soft Basic on a PDP-10 at Harvard, running their homebrew 8080 emulator. Allen’s love for the PDP-10 drove him to a full restoration of a KA10 in the 2010s. And in fact, when that restored machine came to life, it gave us the one and only opportunity to check our our replica against a live real machine. Sadly, Allen passed away just before the restoration was completed, and the future of
The Last KA10 looks dim now. Making us even more grateful for that tiny time slot in which we could perfect the replica's behaviour.
