Super Kit/1541 was sold by Prism Software around 1986. It included many different copiers like a Normal Copier, Nibbler, File Copier, Super Nibbler, Disk Surgeon, Editors. There was also parameters on Side-B (see the list below).
I was told that version #1 was very picky about the drive being use and the speed had to be exact or it wouldn’t make working copies. Version 2 worked much better.

Superkit was a powerful copier for it’s time period.
The program played music during the dual drive coping.

Interesting fact is that the program could make a copy of itself,
BUT could not make a copy of the copy.

PROTECTION on the disk: Custom format – extra tracks to 38 and all density 3 except track 18
To Copy try: Shotgun V1 (not V2) with density detect on T1-T38. If that doesn’t work lower your drive speed to 298 and try again.
