I have an older Sperry Quad Async Communication Board, part number
WSRS4B (I think), made for Sperry by Mitsubishi.  It is for the Sperry
IT (or PC/AT) and has a 16-bit bus connector and 4 (naturally enough)
9-pin D-connectors and 16450 UARTS.  Alas, it also has two jumper
blocks, about which I know nothing.

Can anyone suggest a source of documentation for this board?  I need to
know how to configure the jumpers to select the interrupts and I/O ports
for the four serial ports.  The local (Seattle) Sperry sales office
wasn't of any help the last time I called them (a long time ago).  A
pointer to someone technical at Sperry or anyone with a little
documentation would be appreciated.


Thanks,
Joe
