My googling did not throw it up.
36 way mini-centronics connector, which pins for ,primarily, SVGA
connection and secondly serial Rx/Tx pins.?
Dumpster dive projector , managed to repair power supply, but no
semi-proprietary lead with it of course. A previous Infocus projector I
made up a semi-proprietary M1 connector and lead and worked out the
pinning , but anyone been here before for another Infocus? I'm not
convinced there is a genuine supplier of these in the UK and 50 dollars
+??? if genuine
You sure this is IEEE-1284? That is usually used for printers and
scanners, and is basically a standard bi-dir printer port with some
different use of the signals. If it really is IEEE-1284, then
there are a number of references online to the pinout, signalling
protocol, etc. Know that IEEE-1284 and EPP parallel port are the
same thing. Some of the places that have info are Warp 9 Engineering
and the Jan Axelson book.
