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 ?

CORRECTIONS:
10:17 To clarify, only the Amiga GCC toolchain we were initially using at this point does not support Fortran, but GCC overall and in other versions does, as we demonstrate later.
10:47 Even though the Amiga has a single-thread processor, it can run multi-thread software, which was essential as the only software we could find that could work was multi-thread. 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.
