Back in the day, sideloading was perfectly normal; not something to be frowned upon. Case in point.

@npub1sny…ax7g I think I see Zmacs editing Lisp code.

I'm sad to learn Gordon Bell passed away on May 17th.

Music keyboards have long lagged behind the more evolved computer keyboard with regards to user friendliness. But I think I have found a solution.

Microcode and the TENEX monitor is available from the Xerox PARC archives that the Computer History Museum made available a few years ago: https://xeroxparcarchive.computerhistory.org/indigo/maxc/.index.html

When Xerox PARC was refused a PDP-10 from the competitor DEC, the researchers built their own clone. #OnThisDay 46 years ago, their 𝘴𝘦𝘤𝘰𝘯𝘥 clone went online on the ARPA network.

@npub19y8…wxgj @npub1jjz…09ct Thanks! I'm not sure either, maybe just whether the speaker says something particularly interesting.

If your computer is riddled with minicomputer software from Bell Labs, get yourself a PiDP-10.

#OnThisDay 46 years ago, Multics Emacs was started.
I'd like to seize this opportunity to correct a persistent rumor that Multics Emacs was the first Emacs written in Lisp. EINE predates it by about a year.

Good news everyone! Bob Supnik's MIMIC simulator suite has been found, and will appear on GitHub shortly. MIMIC is written in MACRO-10 and runs on the PDP-10; SIMH is a reimplementation in C.

@npub13d8…ycpx Geez, those BBS messages are really innocent. Call a public phone number and enter some TIP commands. Not much of a "penetration" of the ARPANET.

Here's a photo of MIT's XGP printer. There's a PDP-11/20 to the right, which is driving the printer with data sent from the AI lab PDP-10.

Lisp — putting the "fun" in "funcallable".
