That's right; I'm using a 3.5 inch second drive containing an ADFS L
disc so I can use my A310/A5000 to read the disc and write it back out
in MS-DOS format for my PC to read. (A couple of people suggested I
could use DOSFS on my Master to avoid this step, but it didn't work
when I tried it. I'm guessing DOSFS doesn't support OSGBPB, but I
didn't investigate properly.)

In theory I'm sure a program could be written to read as much as
possible into memory at a time and prompt the user to swap discs,
allowing it to work with a single drive (analogous to the way *BACKUP
works), but I doubt anyone would ever bother to do so.
