Yeah, it'll work as an Amiga PC drive, if I remember correctly.
Capacity is only 360K. Standard DSDD PC floppy capacity.
Guess it would still be usable for PC task or such.
And the Transformer program was REALLY slow.
Not sure about which Kickstart, but I do seem to remember there was/is a patch on aminet to make it more compatible.
The A1020 drive will work as a regular Amiga drive (although only half the space). As I recall the Transformer program ran at PC/XT speed with slightly slower I/O access, in monochrome green, and only with KS version 1.1 -- but that has been 30 years ago.
