I have an HP7221 plotter which was purchesed in good shape for the right
price.  Since the 7221 uses the rather old HP binary format I would like
convert it to a 7220 which is hpgl.  I know this has been done before by
changing at least the ROM board.

Does anyone know how this is done and the approximate price?  How about a
number and/or name at HP I can call?   Part numbers?

Any help will be sincerely appreciated.

Thank you.
