Have you tried


or typing in a 1-2 line BASIC program and


I have a similar product, a PETdisk -

It does not work with DIRECTORY but it does work with LOAD"$",8 (with
the firmware I have, which might be one rev old, I have to check

I haven't tracked down bus-transaction-by-bus-transaction precisely
how DIRECTORY is implemented in the BASIC 4.0 ROMs, but ISTR in the
DOS Wedge, the code does _not_ do the exact equivalent of a 'LOAD
"$",8' but rather does an 'OPEN"$",8' and reads the bytes and does a
small amount of formatting/trimming of the raw stream before printing
the results.  If someone who _does_ know exactly how it works could
comment, I'd love to hear the difference.  I've also skimmed over the
code for the 1541 drive and I think LOAD"$",8 and OPEN"$",8 do similar
but not exactly the same things.

Not sure about reading DS/DS$.  That's also going to be
emulator-specific and I don't have the same product as you, even if
the DIRECTORY/LOAD"$",8 problem could be similar.
