I am findting no love [documentation-wise] on the Fanuc Parallel
Interface adapter, IC647WMI620 / WS6AI.

Mike Lycett sendt me feelthy-feely images of the -620 daughtercard and
main card, there is a pair of 8-bit bitslicers on it, 29 tiny SOC fuses,
and seven [IIRC] 16 pin diode DIPs [8x diode per device]. Some SIMMple
discrete logic, 11 SIPP resistor networks...

I have no idea of what flavor of parallel we have, that is a helluva lot
of protection for a lowly printer port. There is ZEERO discrete parallel
controller on the daughter -OR- base card. It has two eight position DIP
switches with NO legend. On an MCA card.

My spidey senses tingle with visions of RS-485 configuration akin to the
OPTO-22 brain boards. My SWAG those set the address and termination for
a multi-drop RS-485, and I wandt nothing with flipping those switches to
all 16 squared combinations.

Happiness is twin floppies.
