I had a look at OSNews.com and found a story about a nifty little terminal and its OS called Blit. http://www.osnews.com/story/26315/ Blit_a_multitasking_windowed_UNIX_GUI_from_1982 I suspect getting hold of it would be like getting blood from a stone, much like getting the Research Unix source trees ... but still it would be interesting to look at if at all possible.
