Deep Dive: Commodore's Fast Serial Bus Protocol Explained

This episode digs into Commodore's serial bus protocols, starting with the VIC-20 and Commodore 64 with their extremely slow disk I/O, then moving on to the Commodore 128 and 1571 where Commodore implemented fast serial protocol. I cover the history behind the evolution of Commodore's serial protocols, and I do a deep dive into the technical details about how they worked, including tracing bus signals with a logic analyzer and explaining it every step of the way.
