Jay, I'm not surprised that you've reversed-interfaced a display - this was a popular pasttime, 22 years ago! Mine was a VFD, also showing radio station frequencies, but the idea was to display the station name from a look-up table.

Bruce, if you don't need to process the results of your calculations, you could simply take a snapshot of the display via a camera on your PC. If you *do* need to process the result, use the same deal, but *fix* the camera above the calculator (to keep the image constant), then write a program to analyse the bmp files!

Regards,

Richard
