Thanks for that. Is the MSD SD-2 a Commodore drive? If not, who made them? I
guess these drives are pretty rare now.

André Fachat designed a IEEE-488 <-> IEC interface, I believe he has
the schematics on the web. Requires two driver chips that you probably
won't find though. The 64'er schematics were for converting the 1541
to IEEE-488, and I think they also published schematics for an IEEE
interface for the C64.
The best solution is probably to get an MSD SD-2 -- it has both
IEEE-488 and IEC connectors on the back, and is 1541 compatible. The
other option would be a 20/30/4040 or 2031 drive, which can all read
1541 disks (and vice versa).
