Perhaps I didn't read your message close enough, but which hardware would 
one need to perform the action? I see in the shell script you reference to 
xum1541, so I assume one needs an interface compatible with that one, 
probably the ZoomFloppy? For instance, I only have regular XM1541, C2N232I 
and could probably hack together a PC64 cable, but I understand neither 
would be sufficient unless you produce a PET binary that will send the 
floppy routine, retrieve it in RAM and store elsewhere. Since it is possible 
to dump e.g. 8050 floppy disks through cbmlink (C2N232, PC64 cable etc), I 
suppose it should be possible to send the routine and retrieve the ROM data 
over the same line?

While I'm sure ZoomFloppy is the answer to most of our needs, many of us 
don't own it yet which would pose a problem in helping you with the dumping.

Best regards
