Commodore History | The gory details: What happens when you save a file from a Commodore 64 to a 1541 disk drive? @commodorehistory | Uploaded December 2021 | Updated October 2024, 3 hours ago.
If you're curious about how a Commodore 64 writes data to a 1541 drive across the IEC serial bus, this video will shed some light on that. I connected a logic analyzer to an IEC cable and captured all the bus traffic when I saved a Hello World program to a 1541 disk drive. In this video I walk through the captured traffic and explain the basics of the IEC bus protocol.
