comparing against ncurses
ncurses's name for the Tandy-100 appears to be dt100 (rather than td100), which came from the SCO (Xenix) terminfo in 1996. There are several differences, which you can see using infocmp. Without some documentation (or testing with a real Tandy 100), there's no way to resolve those.
Thank you, Mr. Dickey. I am grateful for your expertise.
I have contacted a gentleman from the Seattle Retro-Computing Society who owns a Model 100 to test the differences.
The Xenix terminfo Tandy put in their documentation for the 200 was incorrect and incomplete. I suspect it will be similar for the 100.
By the way, how did you find out about my little project when I haven't announced it yet?
I think the dt-100 might be different than the Model 100. Radio-Shack also sold a dt-100 "Data Terminal" as seen here:
