What do these settings mean? 2) Where do I read/set the clock/calendar? Is this at a standard port? 3) The card has a rs-232 serial port and a parallel port as it sits now. It seems to be expandable by two more (parallel?) ports, but there is a 40-pin and several smaller chips missing. What fills the holes and will that give me two more parallel ports? Any help would be appreciated. I haven't called the company because the thing is so old, and because I'd like to get a schematic too, if possible. -wes schreiner nuschrei@plains.nodak.edu
