Someone actually mined $BTC on a 1983 Apple II with an 8-bit processor.

The madman had to jerry-rig 32-bit operations from scratch since the hardware wasn't built for SHA-256. After optimization help from programmer Peter Ferrie, they squeezed out ~3.8 hashes per second.

Setup: Modern Mac feeds mining work to the Apple II via virtual floppy disk over serial connection. A pixelated Bitcoin logo spins when new work drops.

The punchline? At current difficulty, this setup would take an average of 256 TRILLION years to find a single block.

Pure degen energy for the culture. Zero profit motive, just proving it can be done. This is what peak Bitcoin autism looks like.
