Thank you, Mike;
In looking at the parts inside the case, yes, it is from the middle 1980's. My guess from looking at the date codes on some of the components inside is that it was made probably around June of 1985. Why am I looking around inside? Because I am an electronics technician, and I do that kind of thing.
The circuitry inside is quite straight forward, and identifying the major functional sections is easy. How some of the logic sections work is a little bit more difficult. I had hoped that there might be someone on APUG who might recognize the name, and perhaps would know where I can find the company, or their successor, or where information about this unit might be found.
My end goal is to locate a schematic or service manual for it to aid in keeping it going.
Again, thank you, Mike, for offering your reply and comments to my inquiry.
