Yes thanks!  I was looking at that.  However, the model show there is
slightly different than mine.. mine doesn't have the keypad on the front.
It only has a power and reset key.  I assume as Chuck suggested to me
previously there is a way to pass commands via serial to get it to do
something.. but I've not found any info on what you need.

I found some interesting information about it in the Appendices of this
technical report:

Apparently the product was used in several documented data acquisition
applications over the course of the early '80s.
