This list of Lisp implementations published in 1987, some of which obscure, is a snapshot of what the market and academia offered for various machines. Although Symbolics Genera's Common Lisp is listed, Interlisp is conspicuously missing, probably because nobody at Xerox submitted the information to the editor.

"The Harmony Compiler works by switching the bulbs on and off fast enough to create audible square waves when the light bulb outputs are wired to a simple audio amplifier."

I don't have to think about the possibilities. I *have* an Atari 800 😎

Using a SPARCbook to play DOOM
My school acquired a computer lab in 1980 and I got to use a CP/M machine with 8" floppy disks. Don't have any of them any more, but I did indeed use them in my teens.

@cstross I really enjoyed explaining 8" drives in my video about War Games https://youtu.be/p-B1clodRJ4 - it was sort of amazing how many people had never worked with them or seen them.
(My personal relationahip with that movie is my dad did in fact have an Imsai 8080 with 8" drives, but they were not "IMSAI" branded drives. He was such a poser.)

RetroChallenge announced the results of RC2024/10 and I'm honored to be among the winners. I entered with the WebCard project written in Interlisp, a NoteCards extension for visiting websites.
Thanks to the organizers, voters, and judges and congrats to all the entrants, especially @psychotimmy who won the Grand Prize.

Picking up this project from two years ago, I finally printed a bezel and key set for my PocketCHIP. I printed it with Polar Retro Platinum and used waterslide decals for the key tops and badge with Univers 57 font.
A PocketCHIP hand held computer on a desk using a #2 pencil as a stand. The case is in a warm beige color with round keys. On the screen is the Flying Toasters screen saver from After Dark.

A document is open showing cursive hello. On the desk is a rainbow 3D printed cursive hello in front of a Lisa computer and keyboard.
Totally stunned that the Pico MZ-80K won the "general" category in last year's #RetroChallenge! Thank you to everyone who voted for me, followed the project, etc. etc. etc.

That Time Ken Thompson Wrote a Backdoor into the C Compiler
｢ he was expected like other Turing winners to write a paper that would be published in the ACM Computer Journal. What he ended up submitting was a paper about "the cutest program [he] ever wrote"-- a sneaky undetectable self-reproducing "Trojan horse" backdoor in the C compiler that would allow him to log into affected machines as any user ｣

Some neat info about 70s hard drive contaminants.

Those funky cool kids at Commodore have sent me another unsolicited email, this time with the font colour set to white so it's invisible. I guess every single person there only uses dark mode and never considers that some of us need light to see things.
Screenshot of an email that's mostly a blank white page with a row of various emojis down the left side

🍏 The Apple Network Server MacOS ROMs have resurfaced
｢ The 1996 Apple Network Server was Apple's first true Unix-through-and-through server (the Apple Workgroup Server 95, actually a Quadra 950 with a special PDS card limited to A/UX, doesn't really count) and through a complex history came to run IBM's AIX as its native operating system ｣
