can use it to interface to a Centronics interface printer.
I don't have the schematics (I do have an LC8-P somewhere), but I
remember back in the day, people wanted to go the other way - feed a
PC printer w/Centronics interface from a DEC interface.
There some discussion of this here...

I don't know if Berg pin S on the LC8-P is a mode select like it is on
an LP11/LPV11 (perhaps the LC8-P doesn't switch modes), but it
shouldn't be hard to trace that out. The data and handshake lines
should be at the same positions or the LC8-P wouldn't be able drive an
LA-180.
