Andy: To put if formally, "They AIN'T no setch board!" Your software, if
you BOUGHT it, should already somehow "know how" to toggle appropriate bits
of the printer-port. I did my OWN, and use GWBASIC "FOR-NEXT loops" to
generate the # of steps needed for whatever move, and then use a simple
ASM-86 patch to "toggle" the respective bits of the printer-port. Bits 0 and
1 are CW and CCW for "X", bits 2 and 3 are CW and CCW for "Y", and the
remaining 4 control the lathe spindle and tail-stock valve. Home brew.

Lotsa luck! Jan Rowland
