I used it for https://tmbasic.com to build an IDE in the style of Turbo Pascal for my toy language. Originally, I was going to implement the TV wrapper framework and UI builder in this project instead, so you could write TUIs in TMBASIC, but that ultimately felt like a waste for a toy language. With .NET someone might actually use it :P

I've sent you an email with the Turbo Vision books in Markdown, if you didn't receive it, hit me up via the email in my profile.
