I -Digitizers for the ST?-

 As many may have noticed, a mouse is a very handy instrument for walking
 through menus, creating rectangular boxes etc. For entering subtle graphics
 it is awkward. Just try to enter your signature with a mouse (....).
 The difficulty is caused by the orientation sensitivity and scaling problems
 of the mouse and the fact that we use the fine musculature of the hand in
 normal writing and drawing. Therefore we are searching a digitizer tablet for
 the ST in our project on handwriting recognition and -simulation.
 A 1040 ST could become a graphics workstation, connected to a VAX via the
 serial interface.

II -Ports-

 As I can think of, there are 3 possibilities:

   (a) replacing the mouse by a tablet (this demands dedicated hardware).
   (b) connecting a digitizer to the DMA interface (dedicated hardware).
   (c) connecting a digitizer to an RS-232 interface (general solution).

 Although we prefer solution (c), we want the workstation to be connected to
 the VAX all the time: so we would need a second RS-232 interface for the
 ST in that case.

III -Sampling-

 Another problem we have is the tablet sampling frequency. This frequency
 should be adjustable from 100 Hz (min.) to 200 Hz or up. Also, the tablet
 should *not* have any intelligence since we want to make a time record of
 the displacements of the pen tip.
                             -------
 Any information on this subject (hardware/software) is welcome!
 We would like to convince our officialdom that the word *ATARI*
 is no Japanese for "Video Freak Toys Only".
