Your floppy was plotting all along
Commodore 64 floppy drive has the power to be a computer and runs BASIC
Retro floppy turns out to be a tiny PC, and the internet can’t stop arguing
TLDR: A YouTuber proved the Commodore 1541 floppy drive can act as a tiny standalone computer and even run BASIC via a simple serial setup. Comments split between 'old news' flexes and playful definitions—some say it’s a computer like a car keyfob, others drop retro receipts and Mandelbrot nostalgia.
Plot twist: your old floppy drive had a brain. The Commodore History channel’s Dave proved the 1982 Commodore 1541 isn’t just a disk spinner—it can boot a tiny computer persona, speak BASIC (a simple beginner’s programming language), and say 'Hello World' over a serial terminal. Cue comment chaos. Veterans rolled in with receipts: “We’ve been doing that,” pointing to a C64 scene where demos offloaded tasks to the drive link. One user remembered a fractal art program where “half the image was computed on the floppy drive.” Apple II fans peeked in to declare their drives were “dumb” by design, and the Commodore crowd sipped tea.
Then came the spice. A skeptic shrugged, “this isn’t news”—comparing it to discovering modern PCs can run MS‑DOS. Another commenter got philosophical: yes, the 1541 is a computer, but more like your car keyfob—smart, limited, and not very chatty. Jokes flew: “Next up, my toaster runs Python,” “beige brain unlocked,” and “serial-only life.” Dave kept mods minimal, borrowing the vintage KIM‑1 approach (think single-board basics) and porting Tiny Basic to keep things safe for the hardware. Final twist: now people are eyeing modern drive controllers and whispering, “so… what else is secretly a computer?”
Key Points
- •The Commodore 1541 floppy drive contains a 1 MHz MOS 6502 CPU, RAM, ROM, and I/O, enabling it to function as a standalone computer.
- •Using minimal hardware modifications, the project adapted a KIM-1 kernel to initialize the 1541 and support serial teletype interaction.
- •The modified firmware was burned to an EEPROM and released on GitHub; communication was achieved via a custom USB–RS232–TTL adaptor and Minicom terminal.
- •Tiny BASIC was ported to the KIM-1 environment and installed as a ROM on the 1541, enabling BASIC programming on the device.
- •Due to limited I/O and lack of graphics/sound hardware, the 1541 computer remains constrained to serial terminal use without major hardware additions.
