I used to be a librarian for the 20/64 group and then for 64 More.
I managed to collect a lot of CBM stuff and write a lot too.
My old 80's 1541 disks are forgetting their content and I would like to
find an easy way to save what's left. Unfortunately, I didn't document
my projects well and have versions all over the place. So far I have
used SC and a cable on a PC with 1541 to get what I could but wonder if there
is software for a PC using DOS that will read a CBM disk on an IBM
drive and extract files enmass
directly. I have a dual CBM drive which looks like it uses IBM disk
drives, so I wonder if the reverse might be true. I would like to
go over my CBM source with DOS IBM tools to
expedite the whole process (not to mention slow I.O. for a 1451 or
1581 drive). I still have my C128 to test things on via serial cable.
I imagine there are better ways to do this and software I havn't discovered.
Any help would be appreciated. I wrote a gizmo that gives 50 lines x 80 columns
on the C-128 and some other things that may be useful to others and
would end up putting them on my website (eventually) www.ml1compiler.org

The drives themselves used with PCs can read CBM format disks,
however the drive controller chips in PCs can't be set to read
them. The solution is to use a special programmable drive
controller device that connects to the drive instead.
Currently there is the Kyroflux ( https://www.kyroflux.org/ ),
and before that there was the Catweasel
( http://wiki.icomp.de/wiki/Catweasel ). There might be others
as well. I'm not sure whether they offer a significant speed
advantage over Star Commander though.

You could also look at picking up a ZoomFloppy device. With that you can then
use a 1541 drive or a SDF1001 drive to read and dump the disks into D64 format.
When using the 1541 and 1571 it will read the disk using WARP mode wich is
quite a bit faster than your standard 1541.

Hi Kev,
Thanks, I was looking for an IBM software only solution.
I know that getting a drive and software to simulate a 6502 is a bit
of a problem. The 1571 will read and write IBM disks as-is and the
1581 controller is a standard WD controller. All I want to do is read
and write, no fancy 6052 stuff. Just guessing that if possible then
by now it might be out there somewhere.

The problem is the drive controller chip on the PC motherboard,
not on the drive. Without using alternative hardware to
replace that, I don't think it's possible.
