Winworld has a copy here:
It started out as Textra, but was developed by some U of M college guys right in Ann Arbor MI. I know, because they ran an ad on the U of M BBS for testers. I drove all the way from my home town, decided to invest, and took my security in the form of hundreds of 3.5" diskettes and a 1 page "manual" that was stuffed into a 5" x 8.5" envelope.
I sold these to EVERYBODY.
I don't have any left of my own but my good friend is still alive and I know - absolutely know - he has one some place - but w haven't found it yet.
Anyway: It was a damned good word processor. It did VGA under DOS, was smooth and never glitched. This was at a time when I was a card carrying WordStar fanatic (I even used to get the *.* magazine aka Star dot Star).
Imagine if I had held out until those boys talked Symantec into buying it - I'd be like one of the early investors in Microsoft.
