[comp.periphs] HP7221 to 7220 plotter conversion

larry@tapa.uucp (Larry Pajakowski) (10/15/89)

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.

There is a 4-ROM kit still available that will convert your 7221A/B/C/S from
"compact binary language" to HP-GL.  This effectively makes it into a
7220A/C/T.

The kit is HP part number 07221-00020, and has a U.S.list price of $75.00.
Contact your local HP Sales Office.
