Well, that blows that idea. I don't HAVE any SSSD disks, just DSDD.
Back to the drawing board I guess. I'm getting a little tired of messing
with this thing anyway. I'm stretched to the limit financially right
now, so this is just a side project to keep my mind busy. I don't know
enough about programming in CP/M to get it to do what I want, so I'm
pretty much just using what's already compiled via image disks or building
a few simple .com files with MLOAD. The stupid host terminal turns any-
thing other than simple ascii to shit when you try to save them to disk
after uploading, even at 300 baud. Guess I'll just take a break from it
for a couple weeks, and then maybe try something different. Thanks for
your input folks.

Here's what I've been using for settings
for formatting and writing
disk images.
Tracks 77
Sides 2
Interleave 1:1
Sectors per track 26
Bytes per sector 256
FM @ 500kbps
If I could get 22disk to actually play nice with this thing, I'd definitely
buy a license for it. :))
Well, I think you're making some basic errors. Every PC/Compatible in
the world can write MFM; the FM-capable ones are in the minority (all
standard DOS disks are MFM).
Second, you can't write 26 256-byte FM-encoded sectors on an 8" track.
26 128-byte, yes, but 26x256 is definitely in the MFM arena.
Try formatting up a SSSD 8" floppy using definition A1--DRI's standard
CP/M distro format for years. See if your 820-II like it.
