- The Ultimate Apollo Guidance Computer Talk (2017)
my fourth talk from the “Ultimate” series will take place at the Vintage Computer Festival West 2021 in Mountain View on 2021-08-08 at 12:00.
This talk discusses floppy disk drives, with the 5,25” Commodore 1541 as a case study. We discuss the history of magnetic recording formats, how data is represented on a disk and how it gets from the drive to the computer. We also talk about fast loaders, alternate recording formats, copy protection schemes, and how to preserve disks using modern tools.
