Apricot F1 ?
Apricot DS ?
Apricot was a Apple clone if memory serves.
Then there may have been more than one company calling itself Apricot, or
more than one format, but what I have is a 3.5" MFM diskette.
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.
I, and others, have some Epson Geneva PX-8 diskettes that are 3.5" MFM,
with FORTY tracks per side, at 67.5 TPI! I have read them (have not tried
REwriting) with a 135tpi drive, and I HAVE an Epson 67.5 TPI drive.
It is the only MFM 3.5" disk format that I have seen with 40 cylinders.
It is nice to hear that there was also an 80 cylinder model!
NEC 8201
It ran cpm and maybe MSX.
AND a "stand-alone BASIC" as do many
other NEC models.
In the list..
There were a lot of wild flyers out there. Some were sorta clones and some
tweaked private label units.
Yes, indeed.
I don't have access to my personal files today (family medical crisis), so
I can't even identify for sure which on that list were CP/M style formats,
which were MS-DOS style formats, Stand-alone-BASIC, P-system, etc.
And many had more than one format available or possible.
In many cases, I have never even SEEN the computer itself, and only have
floppy disks from it.
