It's a piece of test equipment that generates bit patterns. The
connectors on the back go to pods that
output different logic levels like TTL or ECL. I used one to generate
test patterns for testing parallel
loaded video DAC's.
It could be programmed to loop through sections of data loaded into it's
internal memory and
respond to input bits to change what it's outputting.
It's main use was for testing IEEE 488 interfaces, but could be used as
a general purpose data
and timing generator.
