Epyx Fastload Cartridge
The Epyx Fast Load Cartridge (1984) is revolutionary accessory for the Commodore 64, released in 1984 and programmed by Scott Nelson—formerly of Starpath and later the architect behind Epyx’s Vorpal fastloading system.
Designed to dramatically reduce loading times from the notoriously slow 1541 disk drive, the cartridge delivers data at approximately 2,500 bytes per second—up to five times faster than the default rate.
What makes the Fast Load so popular is its simplicity: no hardware modifications were needed. Users simply insert the cartridge and immediately benefit from faster load speeds.
