[comp.sys.ibm.pc.hardware] Help with Async Card

davids@epicb.truevision.com (David Spoelstra) (01/15/91)

I inherited two async cards, and I need help to get them to work.  They are
half-length cards with a single DB-25 on them.  Looking at the component side
there is an 8 pin DIP jumper block in the upper right labeled U15 and a 16 pin
DIP jumper block in the lower right labeled U5.  The only other jumper is in
the center of the board and it is labeled J13.  On the upper left is a
1.8432 MHz crystal oscillator and the VLSI chip is an 8250.

Can anyone identify these cards and help me setup the jumpers so that I can
put them in my AT clone??

Thanks,
David Spoelstra
