The Dysan
3.25" was kinda neat. Dysan bet the company that the
"shirt pocket" disk (3", 3.25", 3.5", 3.9") that would
succeed
I've always felt that the 3" (Hitachi) disk, as used by Amstrad, was
mechanically superior to the 3.5" disk...
... except when the rubber band wore out. You could often get away with
adjusting the tension, but when the belt was gone, it was new drive time.
Or was it? Digging through a pile of scrap bought from another shop that
had gone bankrupt, I discovered that one of the belts in a Ferguson 3V24
belt kit fitted pretty much perfectly, but was made of slightly thicker
rubber. This was in the dim distant mists of 1991, when I used to get
about half-a-dozen PCWs with dying floppy drives through the shop every
week.
Nothing else ever went wrong with them. Ever. After WWIII when we have
all perished in nuclear flames, the only living things on Earth will be
the cockroaches, and they will be typing up their stories on Amstrad
PCW8512s.
