The KIM-1 was an amazing little machine. It ran a whole universe of programming languages: BASIC, PASCAL, FORTH, FOCAL, VTL02, PILOT, and COMAL. But it wasn’t just about languages — there were so many practical applications too:

1C00. Where it begins.

I finally got SUPERMON going on the KIM-1 netzherpes.de/post/supermon Thanks to all the work that has been done previously by Jim Butterfield JB Langston Andrew Taylor

50 years of KIM-1! The birth can be traced to January 1976. The sale ended in 1981. KIM is Dead!!! Long KIM!!!

The KIM-1 was designed to be a practical demonstrator board for the shiny new 6502 microprocessor, but became a cult computer system in its own right.

And also availabe on Tindie is the PAL-2, a full 64 kb equipped KIM-1 clone. Better than the original with a USB-C connector

Insight of the day: The crunching tool “Exomizer” is not only useful for the C64, it also works with the KIM-1. Nice surprise – old tools, new use cases. 🚀 csdb.dk/release/?id=... #kim-1 #c64 #commodore #65o2

The KIM Uno is a project that uses a modern (ish) microcontroller to make a pocket KIM.

Why is the KIM-1, s slow and minimal Computer so relevant for computing history? Let the pope Jim Butterfield tell you: groups.google.com/g/comp.sys.c... :

An original KIM-1 is expensive these days. To get a clue what this computer was all about, you can emulate it - here are several emulators: Hans Otten's Win / Linux retro.hansotten.nl/6502-sbc/kim... John's iOS apps.apple.com/us/app/virtu... Maksim's Browser maksimkorzh.github.io/KIM-1/ #kim1at50

The great thing about the KIM-1 is that if you don’t have an original you can build yourself a clone. Here is a PAL-II you can find on Tindie beside an original.

Your first KIM-1 program! www.kim-1.com/docs/usrman....

Here are mine. A rev G KIM-1 and a licensed clone from Digitus of Sweden, serial number 008. #KIMat50 #ShowYourKIM1 #KIM1 #RetroComputing.

50 years of KIM-1 and me retro.hansotten.nl/50-years-of-... I have collected some KIM-1's over the years. The first KIM-1 in 1978, and now I have nine original KIM-1s, from first edition to Rev A, B, D, E , 2x F, 2xG. And several reproductions with 6532's as replacements.

🖥️🎂 The KIM-1 just hit level 50! Own one? Clone? Let’s SEE IT! 👀 Post your machine! #KIM1at50 #ShowYourKIM1 #RetroComputing #KIM1 #65o2

Just a short little video I made about the 6-chip "Simple 6502" designed by Grant Searle. www.youtube.com/watch?v=Ow5G...

Happy 50th Birthday KIM-1 https://github.com/netzherpes/KIM1-Demo (https://news.ycombinator.com/item?id=46575804)

One of the very first _affordable_ computers that could be used by hobbyists was the KIM-1 from MOS (later Commodore). The KIM-1 is 50 (!!!!) this month. github.com/netzherpes/K...

🎉 HAPPY BIRTHDAY, KIM-1! 🎉 Wishing you — and all of us — a fantastic and hacky Year 2026 🥳✨ This is the demos final version: youtu.be/aikJvjdEDto #KIM1at50 #ShowYourKIM1 #65o2 #RetroComputing

The KIM UNO, the little cheap KIM-1 hardware emulator needed some information added. Photos, links, text. Like the recently acquired KIM UNO from retro4004bits, alternative firmware by Willem Aandewiel for better LED display and Keypad control. retro.hansotten.nl/6502-sbc/kim...

Happy new year! 🎆 I‘m reading @indieretronews.bsky.social on my little BBS using @bbswordle.com s feed reader. Thanks for all! Visit www.hackerforce.de

I put up a new video to YouTube about the (brief) role of the Floppy ROM in personal computing history, plus there's a tour of SWTPC 4K floating point BASIC (how-to, patches, demos). www.youtube.com/watch?v=EuT8...

Transform your Commodore 1541 into a KIM-1? youtu.be/6loDwvG4CP8?... Amazing Job of Dave from COMMODORE INTERNATIONAL HISTORICAL SOCIETY #kim1 #65o2 #mos6502 #sbc

I'm trying to set up a landline for my BBS. Is anybody out there able to check if everything is working, pls (I just have one modem... I can not test myself) the number is: +4969294895 #bbs

The Jolt/SuperJolt/TIM Simulator got serial input/output! USe with an an extermnal terminal like VT100 (or PC). Or local terminal emulator with a virtual null modem, com0com on Windows, socat on Linux. retro.hansotten.nl/6502-sbc/653...

Finally a KIM Uno with a newer (and cheaper) Arduino Nano USB-C. A bit messy under the hood, but working like a charm.

Darauf ein Glas »Roundcube«! Dann doch lieber die Rescue-Droppe vom Samenhändler @masterhit.bsky.social.

Remember: Computers are dumber than humans, but smarter than programmers. wisdom from "First Book of KIM"

I’m excited to be one of the people helping to put together this 50th birthday party for the Byte Shop in San Jose this weekend. It’s free and open to the public, and will be an extraordinary opportunity to mingle with some of the folks who invented the PC age. byteshop50thyearbirthdayp.rsvpify.com

Just heard a christmas song by Alwin and the Chipmunks. My wife corrected me. It was Sia.

Good News everyone: Wir haben ein Dach und ein Öffnungsdatum. Für uns startet das Jahr am 03.01.2026 Danke für Euren Support. Ihr seid wahre Museumsretter <3 www.flipperundarcade.de/news/wir-oef...

KIM-1 still going strong! Now need some expansion hardware to get it to “do” something. #6502

Time to update the Kannons ‘N Katapults wiki @kirkman.bsky.social! KNK25 is here with multiplayer kastle wrecking action! The legendary game BBS Door game has been remastered! @a-net-online.bsky.social @hypernode.bsky.social #knkremastered #bbsdoor

My homemade, hand-wired 6502 machine, presented in honor of #ChuckPeddleDay. 32K RAM, 16K ROM, 6850 ACIA, running at 921 kHz. It has the Apple 1 WozMon for a monitor, plus 4 BASICs, FOCAL, and Tiny PILOT for high-level programming.

It‘s #ChuckPeddleDay ! Charles Ingerham „Chuck“ Peddle would habe turned 88 today.

Il y a 88 ans, le 25 novembre 1937, naquit Chuck Peddle, ingénieur américain. Il sera connu pour avoir cofondé MOS Technology et mis au point la famille de microprocesseurs 65xx, notamment le MOS 6502 #LaPetiteInfoDuJour

What a #ChuckPeddleDay surprise. A new #65o2 game console.

For #ChuckPeddleDay, I added an option to load the Oric Atmos ROM (1.1B that is) to the Virtual 6502 online emulator. masswerk.at/6502/

History and basic features of the KIM-1 youtu.be/jj0Hn2ZcW-s #ChuckPeddleDay

The office nerds held a special "show and tell" in honor of #ChuckPeddleDay. Chuck designed the 6502 CPU that made so many home computers possible and led to the microcomputer revolution of the 1980s.

The KIM-1 was Commodore’s first big hit 🚀. If you want to learn more about it and the revolution it started 💡, you can read about it in this book 📘: drive.google.com/file/d/1Xyvj... #ChuckPeddleDay #kim1 #mos6502

The KIM-1 was a single board computer with a keypad and six LED displays designed to highlight the power of the then-new 6502 CPU designed by Chuck Peddle and team at MOS. #ChuckPeddleDay
