There is one interesting(?) bit to how I found this info.
I currently live in the town that TSC once called home: Chapel Hill, NC;
not two miles from their former address.
So I popped in at our Chamber of Commerce to ask if they would have
records of TSC's demise; they wouldn't.
They gave me some hints about asking the owner of that office-building,
contacting county offices, and so on.
I asked around at the library for information on copyrights, and got
the phone number for the archive department in another library.
Then I did a web-search, sent one piece of e-mail, and within two
days had the answer in my mailbox.
That was about a week ago.
Today I thought to look back at the news-articles announcing
"the missing UniFLEX archive", and found the whole story there on
The moral of the story: easy things can be hard if you aren't careful.
(Or: think before you search).
