I picked up a couple of nice A/B boxes with three 25 pin connectors
on them for cheap. I'm thinking of building all of the subject
interfaces into them. Does anyone have a schematic for a homebrew
LPT port band decoder? How about the use of optoisolators in all
of the subject functions? Thanks in advance.
