[Coco] DriveWire printing options

If I'm understanding you correctly, then the initial output from drivewire
will be a RAW dump of the data from the port (whether bitbanger or (if
supported) parallel port).
Then any tool can be used (if necessary) to convert the RAW to either a
picture file or a text file, or for that matter a MIDI file if the output is
Do you envisage support for Ultimuse, which also uses the bitbanger port,
albeit at a different bit rate?

Besides a mathematical inclination, an exceptionally good mastery of one's
native tongue is the most vital asset of a competent programmer.
