 data (

 a 1541 read an Apple ][ disk?  I know they both use GCR encodings for
 their disks, and it'd be really useful if I could read disks on my PC.
 Also, does anyone know anywhere I could get a Compaticard (and any
 necessary drivers to make it useful)? I've looked on ebay a few times now
 and still haven't seen one...

AFAIK, the 1541 only does its own SSSD disks.  The 1571 OTOH does
several cp/m MFM formats.  You could do some limited changing of DOS in
the controller, but it is very limited.  If you can lay your hands on
"Inside Commodore DOS" by Richard Inmers & Gerald Neufeld (ISBN
0-88190-266) you might be able to hack it to read Apple disks.
