     I have an old Magic digitizer that works fine on my Mac512KE.  The
software (apparently) converts a 768x480 8-bit grayscale image to a B & W
patterned image that fits on the screen.  It seems to me that if I knew
the handshaking that goes on between the Mac and the digitizer, I could
hook it to a MacII, write some code, and display it in true 8-bit grayscale.
My question(s):  Has anyone tried this?  If not, does anyone know what the
handshaking looks like?  If not, does anyone know of a disassembler that
outputs to a file so I can reverse engineer the information?
