If your EPROM is larger than the file (e.g., burning an 8KB JiffyDOS image to a 16KB 27C128), you should double the image: copy /b jiffydos.bin + jiffydos.bin doubled.bin . 2. Implementation Methods

JiffyDOS was not a cartridge or an external accelerator. It was a replacement for both the Commodore 64 and its disk drive. Developed by Maurice Randall of CMD (Creative Micro Designs) in the late 1980s, JiffyDOS rewrote the low-level communication routines that governed how the computer and drive talked to each other. The original Commodore DOS used a slow, handshaking protocol that sent one byte at a time with significant overhead. JiffyDOS replaced this with a faster, streamlined protocol that could transfer data up to five times faster without changing any hardware.
