Apricot F1 ?
Apricot DS ?
Apricot was a Apple clone if memory serves.
If so, there were at least 2 'Apricot' computer companies. The Apricot I
know of was a UK PC-incompatible, IIRC with an 8086 CPU. Quite a nice
macnine in many ways.
Epson Geneva
PX-8 (40T/Side) (67.5 TPI You would need to double step,
and might not be able to RE-write (like using a 1.2M drive for 360K))
The PX-8 was
definitely a CP/M machine and I have three. the 3.5" disk
unit was
a "normal" format that could be read on PC hardware.
Read, but maybe not written :-). The drive (I have one, but the CPOU has
died) was a rather odd design. The controller board has a a 6303 CPU,
EPROM, RAM, a 765 floppy cotnrolelr IC, data sparator, etc _and the
read/write circuitry (to link to the drive heard), stepper motor drivers
(driven by ports pin o n the CPU), etc. The drive itself is just a bare
mechanism, and as Fred said, is 40 cylinder (62.5 tpi). You can read that
on a normal PC drive (and the secotrs are nmormal MFM-encoded sectors),
but if you writ to such a disk using a PC 135 tpi drive, you get the same
problem as using a 40 cylinder 5.25" disk in an 80 cylinder drive.
