I've used a Shugart 801R with Imagedisk, and it
works very nicely. I
laid out a small pcb to simplify the connections and could have more
made up if there were any interest.
I would be interested. My wiring of the
adapters looks like a bird's nest, but not wuite as organized. I did by an fdadap, but
I could use some more adapters. What do you do for DS/SS sensing? I ended up using a small
toggle switch.
I use Tandon 848 double sided drives with imagedisk. They work very well, you just have to
keep the heads clean.
Dave Dunfield was invaluable in helping me work thru issues getting
single density to work properly. I ended up with an Adaptec ISA scsi
adapter card for the floppy controller which works well (it's
a 1522a).
I can't say enough good things about Mr. Dunfield nor ImageDisk. I
have made images of Tandy 2000 QD 5.25" disks, Tandy mixed density 8" disks, and
PC compatible disks.
What ImageDisk can't handle I save for the catweasel.

The T2K quads are easy. Nothing unusual there. AAMOF
I seem to recall even being able to make images of
them with WinImage, possibly even reading directly in
Win2K.

catweasel.
I'm curious to know what a catweasel can do that an
imaging program can't...

How well does the Catweasel deal with those?
The Central Point Option Board does NOT do well, although
most of that is due to their software implementation
(it can't copy anything that doesn't have an index pulse!)
One [bored] day we put together a copy protection scheme,
that wouldn't stop DISKCOPY, but would stop Norton fUtilities
and Option Board. Back side of a hard-sectored diskette,
formatted originally with a drive indexing off of hub instead
of sensor.

It depends pretty much on your coding skills--but I've had very good luck
with some really oddball recording schemes. Of course, I was just reading
the diskettes, not making copies. That could be a different kettle of
fish.

What defeated almost all copy-protection schemes was that, at some point,
you have to have the executable code in memory and a determined cracker
will figure out a way to defeat all of your lovely protection code.
All you can hope for is that it slows the crackers down a bit. Make it too
hard and they feel challenged and just redouble their efforts.
Cheers,
Chuck
