The KIM-1, short for Keyboard Input Monitor, is a small 6502-based single-board computer developed and produced by MOS Technology, Inc. and launched in 1976. It was very successful in that period, due to its low price (thanks to the inexpensive 6502 microprocessor) and easy-access expandability. - Wikipedia

Discovered this very early historic home computer from my morning music "On the Other Ocean the debut studio album by American composer David Behrman,.. Considered a pioneering work of computer music, the album pairs electronics controlled by a KIM-1 computer with live players."

Predictably and wonderfully, we can build one ourselves.

I'm a bit ashamed to admit that I once owned a quite extensive list of "unintended" opcodes in then popular microprocessors like the 6502 or the Z80, but somehow lost it after having finished university and moved on to later technologies. 😭

So, at some time between the end of the 80s and now, my virtual cat or imagined dog must have eaten it. 😉

May be you can still find that stuff on the interwebs, hidden somewhere in between all that AI slop. Wikipedia might help you.

To give you a hint from ancient memories: The Z80 could architecturally access its registers in both 8 bit and 16 bit chunks - except for the IX and IY ones. Documented as index registers like the well-known HL one (i.e. concatenated H and L), they were portrayed as non-splittable. But they were as people found out, giving you more independently manipulatable registers for situations where you could take advantage of that capability. The IX/IY prefixes were functional pretty much everywhere. Later implementations of the Z80 architecture may have lost that undocumented capability.

`We have published several retrospectives highlighting Intel’s 4004, and it was indeed pivotal to the development of the PC and the industry that holds many of us in thrall to this day. However, there’s an alternative future where the MP944 wasn’t kept secret for over a quarter-century, and one wonders what the shape of the computer industry would be in that case.`

PyCon AU (the finest vaguely-python-related-things conference in Australia and quite possible the entire world) is on in Melbourne again, September 12-14 2025!

I'll be there talking about the eerie parallels between the #microprocessor and #cell_biology ... and there'll be a lot of other interesting and probably more useful things to learn about too: pretalx.com/pycon-au-2025/sche

Según una cita de Michael Slater (que creo una colección para el Museo de Historia de la Computación), en el Microprocessor & Electronics Forum de 1989, los oradores principales argumentaban que los procesadores de computadora jamás llegaría a rebasar los 50 Mhz. El mismo año salió a la venta el procesador 80486 de Intel con 16 Mhz de velocidad inicial. Este procesador llegó a velocidades de hasta 120 Mhz.

#AtariVCS is a video #game console developed and mass produced by Atari for the home entertainment of Warner, Inc.
With an introduction price under US$200 the VCS became the first affordable and popular #microprocessor-based game console in the consumer market.

The Atari Video Computer System was built around the 8-bit MOS 6507 CPU @1.19 MHz and swappable ROM #cartridges to expand the memory limits of 128 bytes RAM. Initially released 1977 with Tank Combat and later #Pac-Man included, bundled with two #joysticks and a pair of paddles this legendary #Atari console opened up game development, cartridge production, and sales far beyond #ActiVision.

While VCS couldn't challenge #arcade hardware in graphics, flexibility was the advantage and the wood grain finish by Gene Landrum made it stylish on top of that. The #game-market started with only 8 titles like #Pong and grew fast over #Breakout, #Asteroids, #SpaceInvaders, #Pitfall, E.T., Frogger and many more. It was the big selection of games available that made Atari's #console a huge success.

After Sears sold it as Tele-Games Video Arcade for less, the VCS was rebranded 1982 as #Atari2600. Low production costs of $40 kept revenue coming in even when sales prices dropped on average of $125.
15 million ACS and estimated 120 million cartridges been sold before the video game crash of 1983. And the ACS was profitable for almost the next decade, but 1992 after 30 million sold units the production was finally stopped.

Maybe the best thing of our #retrogaming #hardware #illustrations isn't the level of #details, but the proof that You don't need to pay for #Adobe #Illustrator #AI or #PostScript to create #retrocomputer #art in best #vector #quality. Since we use only #FreeSoftware and with the #graphic description open like #SVG, there is no obstacle to be #creative #together. Follow #ITsHistory to see what else you could do with powerful #FOSS like #Inkscape
