A Commodore 1520 Printer/Plotter drawing an Archimedean spiral. The basic program (and misspelling!) is from page 52 of the user's manual.

  • Hello, I have a 1520 printer too, but I can't use it anymore. where do you buy these small pens ?

  • @psgkid They are hard to come by new. All I have are old stock that still work. You can get them still from a couple of online retailers that sell Atari 1020 pens (exact same mechanism). Someone on eBay was selling them recently. The plastic gears also fail, but I've managed to fix them.

  • Wow that sound has brought back some memories of the 80s!! Thanks for posting this video!

  • marble that beauty. ARCHIMEDES is Divine. to АРЧИМ means "i am spending" and ЕДЕН means "one". me the infinite power of eden (1) spent one of my ones and appointed him to be my minister for levers. that is how ARCHIMEDEN came to be. and Greeks later on plagiarize him in Archimedes.
