Interesting. I wonder if IBM was looking at those
drives for use. The seller (or more accurately the seller's father) used to work for
IBM Industrial services in Boca Raton.
Well, the SA300 (single sided version) were not the first 3.5" drives,
but they may have been the first 300 RPM ones with an SA400 interface.
(The Sony 600RPM drives would require more changes)
The SA300 could be dropped into a 5150 (with only issues of mounting
brackets (Erector set) and power connector) and were supported by some OEM
versions of MS-DOS 2.11. IBM public support of 3.5" began with PC-DOS
3.20.
