I'm an undergrad senior ee at Christian Bros Univ, my partner and I just
finished developing a Data Aq system for the 48SX.  This thing can be
interfaced to any meter as long as the LCD is not multiplexed out.  Were
presently developing a design to interface an autoranging meter.
software we have samples at about 1sample/800msec.  If you are
interested, write me at the address below.  Once data points have been
taken, you process the data as you like with the HP.  We've gotten some
nice results plotting Voltage/current lines for resistors...  All data is
transfered through the IR port, this thing can't damage the calculator
hardware.  If we every can get a working copy of the STAR assembler, the
software would speed up immensely.  Write me at...
