The Commodore PET 4032 & 4040 Dual Floppy Disc Drive.




Did You Know... ?

PET stands for Personal Electronic Transactor ...
it was a bit of a wanky name for the machines, but it was
what Commodore Business Machines decided to call them.
Note: this pre-dated the name of PC or Personal Computers.

The PET's floppy disc drives, usually the 4040 model
(but there were other models) used standard 360K floppy diskettes,
however, you needed to notch the other side of them and flip
them over to use both sides. They became known as 'flippies'.
Note that they had approx the same storage as their
MS-DOS cousins (360K) but used Commodore's own diskette format.
Each side of a diskette held 664 blocks (plus the directory info),
and filenames could be up to 16 characters long.
