Hi Bill
 Looking at the parts on the board, it is a multi channel
A/D board. It looks like a Standard Bus but I think there
should only be 50 pins. The TSC 800 is a dual slop A/D
( slow but very good resolution ). The AD667's are analog
somethings by Analog Devices. They might be D/A's or analog
swithces.
 It looks like there is a bunch of input amplifiers. This could
be for anything from a simple A/D to a temperature measurement
board.
 Anyway, it is definitely and analog interface board.
