🎄💾🗓️ Day 18: Retrocomputing Advent Calendar - Commodore 64🎄💾🗓️

The Commodore 64, released in 1982, is one of the ones we keep hearing got many people their start in their own computing history. Powered by a MOS Technology 6510 processor at 1.02 MHz and featuring 64 KB of RAM, it became the best-selling single computer model of all time, with an estimated 12.5–17 million units sold. Its graphics were driven by the VIC-II chip, capable of 16 colors, hardware sprites, and smooth scrolling, while the SID (Sound Interface Device) chip delivered advanced audio, supporting three voices with waveforms and filters, making it a lot of fun for gaming and music.

Featured a built-in BASIC interpreter, allowing users to write their own programs out-of-the-box. The C64’s affordability, large software library, lots of games, productivity, and educational applications made it a household name. It connected to TVs as monitors and supported peripherals like the 1541 floppy disk drive, datasette, and various joysticks. With over 10,000 commercial software titles and a thriving homebrew scene, the C64 helped define a generation of computer enthusiasts.

Its impact on gaming was gigantic, iconic titles like The Last Ninja, Maniac Mansion, and Impossible Mission. The C64 also inspired a demoscene, where programmers pushed its hardware for visual and audio effects. The Commodore 64 remains a symbol of computing for the masses and creative innovation, still loved by retrocomputing fans today.

And…! An excellent story from Jepler -

== While I started on the VIC 20, the Commodore 64 was my computer for a lot longer. Its SID sound chip was a headline feature, and many of my memories of it center around music. Starting with Ultima III, each game in the series had a different soundtrack for each environment (though each one was on a pretty short loop, it probably drove my folks nuts when I would play for hours). There were music editors floating around, so I tried my hand at arranging music for its 3 independent voices, though I can't say I was any good or that I have any of the music now. You could also download "SID tunes" on the local BBSes, where people with hopefully a bit more skill had arranged everything from classical to Beatles to 80s music.

Folks are still creating cool new music on the Commodore 64. One current creator that I like a great deal is Linus Åkesson. Two videos from 2024 using the Commodore 64 that really impressed me were were a "Making 8-bit Music From Scratch at the Commodore 64 BASIC Prompt", a live coding session (http://www.linusakesson.net/programming/music-from-scratch/index.php) and Bach Forever (http://www.linusakesson.net/scene/bach-forever/index.php) a piece played by Åkesson on two Commodore 64s.

Like so many things, you can also recreate the experience online. Here's the overworld music for Ultima III: https://deepsid.chordian.net/?file=/MUSICIANS/A/Arnold_Kenneth/Ultima_III-Exodus.sid&subtune=1 -- the site has hundreds or thousands of other SIDs available to play right in the browser.
