No, that controller (I'm suspecting) allowed native Apple ][ access to IBM

Can't say, but probably. I've got an
8" disk here written by an Apple
II. Encoding is weird--basically the Apple RWTS encoded as 8 bit FM
(3740) bytes. Haven't bothered to see from whence it came.
Sorrento Valley Associates sold an FDC for Apple2. At Comdex, they had
it wired to an 8" drive. So, perhaps they supported an FM version of
the Apple2 GCR format?
