Looking for software/docs for MacADIOS 411 product

I recently picked up a really neat peripheral device for very early Macs.
Its labelled "MacADIOS model 411" and is a laboratory instrument interface
supporting both digital and analog inputs and outputs. It communicated via
the seral port of the mac (a 9-pin DIN, so you know it for early Macs!). At
its core is a 6502 cpu and looks to have been made around the mid 80's.

Problem is, I have no SOFTWARE or MANUALS for it. Can anyone help me out?
I've contacted the company that manufactured it (GW Instruments, Cambridge,
MA) and they have no information available on their old device and the best
I could get them to do is post a request on their lunchroom cork board.
I've gotten no response to that in over a month.

Thanks in advance,

John Lewczyk
