JiffyDos speeds up most disk access by 10 to 15 times by using a replacement block of code and using all the wires in the cable.
The story is the C64 and 1541 chips were always capable of fast operation but were slowed down because the little round DIN cable was cheap and widely available whereas the original CBM computers used a cable made only by one manufacturer who couldn't supply enough cables ,and his cables were high priced.
If you buy nothing else for a C64 or C128 get JiffyDos.
It is like getting a new machine.
If you are wealthy or lucky ,get a SuperCPU and REALLY see how a C= program can fly.
