I appreciate everyone's input. Searches on Google and Ebay proved fruitless. I expected to scrap these, and really didn't expect to make much profit. I was really curious as to what could be in equipment this old. The brown topped one is from 1983 and the black topped one is from 1985. Since it seems that most agree that I could break even, I will call it a win for the knowledge base.

I will break them down soon and post my findings.



Thanks again folks
