IIRC, the trs-80 had two allocation units per track, 5

was this done in any other operating systems/computers?
The model 1 was sold for a number of years as a cassette storage ayatem
before people started getting disk drives for them. Tandy, when they
started selling a disk drive was mist concerned with profit and
reliability, compared with cassette. As disk drives and disk doublers
brought a new life to the model 1 after 1980, all kinds of OS's popped up
that har a denser allocation scheme than the original trs DOS. It was a
unique case, not many other home PC model had so many OS's to choose from.
