Speed DOS
Speed DOS and Speed DOS plus is likely the best known speeder based on ROM replacements for the C64. It requires a Parallel cable and a modified disk drive ROM next to the C64 Kernal ROM to fully operate. The name was spread a lot due to many programs (mainly copiers) picking it up whenever a parallel cable was required.
Even though many people know the name of this ROM the user base is probably near zero nowadays and most people looking into adding a speeder to their system nowadays turn towards Jiffy DOS. Speed DOS was rather popular in the 80s due to it being easily cloneable by just copying the ROMs and adding the parallel cable to the drive. Still it is a quite slow speeder easily outrun by about anything else.
