The Commodore 1572 was a dual floppy disk drive designed by Commodore. It reached the prototype stage, and was introduced at the Consumer Electronics Show in 1985, but was never released to the public. One reason it was never released was that the code of the 1572 had compatibility problems.
Technical aspects
The Commodore 1572 was a dual version of the Commodore 1571 single disk drive. It had four times as much RAM as the 1571, and twice as much ROM. The 1572 allowed for fast disk backups, much like the old 4040, 8050, and 8250 dual drives.
