[comp.sys.ibm.pc] Need info on an old I/O card: AST I/O Plus II

nuschrei@ndsuvax.UUCP (wes schreiner) (09/28/89)

I need the user info for an old AST I/O Plus II expansion card, circa '83.  

1) There are two sets of jumpers, the first is labeled IRQ and has settings
for {5C,5S,4,3,3S,2C,2S}; the second is unlabeled and has settings for
{C1,C2,S2,P2,P1,G}.  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.
