[net.micro] HP-7470A digitizing

burgee@BRL-TBD.ARPA (BDB-FDT) (07/09/85)

For plotting I use an HP-75C unit with a HP-82913A monitor and a 
HP-7470A plotter attached by a HP-IL interface loop.  My plotting
programs are written in BASIC combined with the HP-GL graphics
language.  Plotting works fine but now I wish to use the plotter
for digitizing.  My HP-7470A Graphics Plotter Interfacing and 
Programming Manual states on page 11-6 that "At the time of this
printing (May 1983), the I/O functions necessary to obtain data 
from the plotter are not available for the HP-75...".  

Does anyone out there know if digitization with the hp-75C and
HP-7470A combination is possible or where I get information on 
this subject?  I have read all my HP manuals and they are no help.

                                    Thanks in advance,
                                    Larry Burgee

The I/O Utilities package (P/N 00075 - 13013) or the I/O ROM 
(00075 - 15001) will allow you to input from your plotter.  For more
information I would suggest calling the HP Technical Calculator Support
Group at (503) 757 - 2004.

(I would have mailed, but didn't know how to get to an ARPA address)

The HP-75 equivalent of the HP-85 Printer/Plotter ROM should now be available
from the HP Users Library.  This is in the form of a cassette tape which
contains a rom image.  The rom image is loaded into a Plug-in Module
Simulator (HP 82713A -- I think the price is around $400).  This unit is
a ram based box that can hold 2 8K roms and looks like a plugin rom to 
the HP-75.  The rom image for the plotter rom implements functions for
plotting, moving, scaling, axis drawing, etc -- and digitizing.
