Syclone is a Resident System eXtension (RSX) program that adds new tape-to-tape copy commands to the CPC 464 from Pride Utilities.
The utilities allows you to backup your tapes and have a choice of seven different saving speeds.
The speeds ranges from 1000 to 4000 baud, and the program is not required to load back tapes saved at high speeds.
As this is a RSX program, the utilities are available from within Basic, and also includes an utility to load and list protected Basic programs.
