Jerome Fine replies:

If you have a 5 1/4" RX50 floppy drive on a real DEC PDP-11,
then it is probably much faster and easier to prepare
the floppy on the PC with PUTR in the first place.  If
the floppy is 8" and SSSD (RX01), then I understand that
a PC can also have the same, but I don't know if PUTR
can also handle 8" SSSD floppy media on the PC.  In any
case, I have no experience with 8" floppy media on a PC.

I am certainly NOT saying that a TU-58 is a bad solution,
only that other solutions are often better if they are
possible.  If the only way to start is with a TU-58, then
it is certainly better than nothing.

Sincerely yours,

Jerome Fine
