Digitizer to output coordinate pairs

#4538

I have a particular application whereby I need to trace over a picture
(actually a series of contour lines) using a digitizer and save the
location data of the digitizer crosshair into a file.  We currently
have an ancient ( ie greater than 9 years old) digitizer which outputs
coordinate pairs ( x,y locations) to a file via a serial connection.
This digitizer is on its last legs.

I would like to get a digitizer 'system' for the Mac which will do
this for me.  However, I have talked to CalComp and Kurta and they do
not know of any way to have the digitizer location data come across
into the Mac and become x,y pairs which can be dumped into a file.  As
with Mac ADB mice, etc  the locations are interpreted as motions on
the screen.  So how could I get the location data and have it dumped
into a file ??

One scenario is to startup a word processor program or communication
program whereby input can be saved.  Then invoke a DA, or 'something'
which will translate the digitizer signals to x,y location pairs and
write them to the screen.

Can anyone help me out here please ??

Thanks,
