The LEDIP text editor or MicADE, a database program called Datensuche, calculators, a clock, a banner printer, and even music programs. A tiny computer with a huge ecosystem. 🚀🖥️

Which transistors are used int he KIM-1 and clones? The LED driver and serial circuit require transistors. MOS used 2N5371 and 2N5375, in later KIM-1s a wider variety. A question in forum64.de in the Nachbau KIM-1 thread made me look at my KIM-1 retro.hansotten.nl/6502-sbc/kim...

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

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

But you can’t beat the real thing. Look at those yellow capacitors!

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.

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

Not only Edison, but the Solo OS with Concurrent Pascal by Per Brinch Hansen, can run in simh: pascal.hansotten.com/2026/01/13/s...

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.

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...

The KIM-1

Back when computers were new, they required good documentation (sadly this practice has ended for the most part). The KIM-1 had EXCELLENT supporting manuals.

🎉 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 Edison system, language and OS. Per Brinch Hansen, the master of simplicity in IT. Book from 1982, disks dumped in 2025, files extracted in 2026. And with simh you can run the Edison system. pascal.hansotten.com/per-brinch-h...

Faithful replica by Eduardo Casino of the K‑1002 8‑bit audio Digital‑to‑Analog Converter card for the KIM‑1, SYM‑1, and AIM‑65 computers, originally designed by MTU in the late ’70s. github.com/eduardocasin...

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...

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

The MCS6530-005 was known to me only by some lines in MOS pricelist and a remark in an OSI appnote as a 6530 without ROM. Today I received a scan of a MOS Technology sheet with the chip equations of the MCS6530-044 and MCS6530-005 (thanks Scott Barnes!). No CS1 and CS2, just I/O ports PB5 and PB6.

And now the KIM-1 Simulator can also use a serial terminal, external or a terminal emulator such as Teraterm, Minicon, Putty etc on the same PC with a null modem eliminator . retro.hansotten.nl/6502-sbc/kim...

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...

The Jolt by Micro Associates, Inc, is one of the first 6502 systems. SBC with 6502, 6821 PIA RRIOT 6530-004 512 byte RAM, a serial interface. The DEMON software 1K OS. Expansion cards 2x PIA, 2K EPROM, Power Supply 4K RAM Tiny Basic, Resident Assembler. retro.hansotten.nl/6502-sbc/jol...

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

All what is known about the MOS Technology 6530 and 6532 from 1975 . retro.hansotten.nl/6502-sbc/653... Used in KIM-1, Jolt, Chessmate, Pinball machines, Commodore diskdrives. Testing and dumping the ROM in the 6530 with the Backbit Chiptester Pro V2:

#ChuckPeddleDay It took some time to finally publish this program for the KIM-1 and today is a good day for it. Udo Juerss is the author. KIM-1 Marquee retro.hansotten.nl/kim-1-marque/ source and binary. Shows running text on a KIM-1 LED display

cott Lombard started many years ago on a replica of the Jolt. Quite a challenge, since only photos are known of the Jolt. He succeeded in finishing a working replica retro.hansotten.nl/6502-sbc/jol... He also made RAM and ROM cards, and made a Tiny Basic Enhancement package,

I put together an electronics kit + book intended as a gentle introduction to transistors and early computer logic gates (resistor-transistor logic or RTL). I set up a Tindie store page for the little over a dozen I have readied. (I'll create a web site soon.) www.tindie.com/products/jca...

The KIM-1 Simulator has seen some small updates, to version 1.5.4 Fresh version at retro.hansotten.nl/6502-sbc/kim... The behaviour of the TTY/LED keypad switch is now closer to how the real KIM-1 behaves.

Wait a minute - Jean-Michel Jarre used a KIM-1 on Equinoxe? C’est fantastique! www.ina.fr/ina-eclaire-...

and also recall what this video led to: github.com/eduardocasin...

KIM-1 Rev D building progress. All passive components acquired and soldered on. Keyboard assembled, will be connected via low profile pin connector. Next step is testing power distribution to all IC sockets. Then the Reset and NMI circuits with the 556 timer.

Were you a Pascal programmer? #coding #pascal

How to build a KIM uno on your own? Order the PCBs from pcbway, order all electronic parts from Aliexpress, program the Arduino, solder everything together, print the case. ( I ordered parts for some more builds - christmas is nigh) #kim1 #kim-1 #65o2

The most popular piece of hardware for the Apple II was made by Microsoft. And it was a Z80. devblogs.microsoft.com/oldnewthing/...
