Product Overview

JiffyDOS is a Disk Operating System (DOS) enhancement which gives your C-64 or C-128 the disk access speed it has always needed. A chip-for-chip replacement for the Kernal ROM in your computer and the DOS ROM in your disk drive(s), JiffyDOS achieves levels of performance and compatibility unmatched by other disk speed-enhancement products. Outstanding speed, solid compatibility with virtually all hardware and software, and a new set of desperately-needed commands and features, gives your system a new lease on life and the power to compete with today's newer, more-expensive machines.

JiffyDOS should not be confused with Cartridges, Turbo ROMs, Burst ROMs or "Parallel" systems. Ultra-high-speed multi-line serial technology enables JiffyDOS to outperform these products without any of their inherent disadvantages. JiffyDOS leaves all ports on your computer open, works with virtually all software, speeds up PRG, SEQ, REL and USR files, and does not require any extra cabling. Owning JiffyDOS also gives you access to some of the best product support available.

Notes:

  • This purchase provides the buyer a license to utilize the downloaded ROM overlay image on one computing device or emulation environment.  Each use must have a separate license for legitimate operation.  Please contact RETRO Innovations for bulk purchase information.
  • The image set contains all ROM images needed to JiffyDOS-equip the C128D, including images for both the C64 and C128 KERNALs as well as the internal 1571 drive.

    Great System enhancement

    Posted by Ingo on 15th Dec 2019

    The JD 128D (plastic) version works great with no compatibility issues encountered so far. Should have purchased this 30 years ago. SD2IEC had some troubles initially but that issue could be traced down to a a substandard serial cable. Unfortunately no international versions and/or no reply to eMail requests.
