I also sent a note to another former Computer Corporation of America employee that I found on LinkedIn. I don't know them personally, but we live near each other and have some common connections, so maybe they will at least receive my unsolicited message with some favor.
FWIW, I did get a response from the individual mentioned above. However they were unable to help with finding a copy of the paper. The search continues...
Someone who isn't me is getting in touch with a computer science librarian at a top 10 university about this paper. I'll update here with whatever I (don't) learn.
