Mike J. Henry of Starpoint Software and Basement Boys Software (Fast Hack-'em) fame wrote a 15 second format routine, which was apparently at some point modified by Alf Maier. I don't know exactly what Alf modified, but I think this was widely distributed on QuantumLink in the mid-to-late 80s. You can download the program from Bo Zimmerman's site here: https://zimmers.net/anonftp/pub/cbm/c64/diskutil/routines/Format%2015%20seconds.prg I disassembled the code and uploaded the result to GitHub: https://github.com/commodoreihs/15_second_format/tree/main Does anyone know the precise history of 15 second format?
