Guy ran $BTC mining on an Apollo Guidance Computer from the 1960s.

This thing navigated spacecraft to the Moon. 70 pounds, 4KB RAM. Never flew, bought from a scrapyard in the 70s after NASA threw it out.

Custom SHA-256 code. One hash took 5.15 seconds. Double hash for mining? 10.3 seconds.

At 2019 difficulty, finding a block would take roughly a million times the age of the universe.

Obviously never mined a real block. Just reproduced an old one to prove it works.

Wild flex but completely useless for actual mining. Shows how far we've come.
