80s Computer Cracks Moon Message: Commodore Amiga Moonbounce!

Moonbouncing with the Amiga: Welcome to Project Moonbounce - a method for sending signals from one point on Earth to another, but can we harness it to receive a message from the Moon then decode it on a #Commodore A3000 with #Linux ?

This setup also theoretically lets the processor use any idle time better. We believe that overall the process was faster than it would be with single-thread software, had we even found any that worked. 19:57 Most of the computers we used in this experiment were 16-Bit. While the final model of Amiga used is actually 32-Bit, Amiga was launched as a 16-Bit product and is most commonly known and referred to by the masses as 16-Bit, which is why we used that general term. It's kind of like how people say "8-Bit" meaning "early computers", even though some weren't 8-Bit. That's my excuse and I'm sticking to it.
