Building TUIs was already super easy in 1990 with Turbo Vision and Clipper on MS-DOS, with compiled languages (TP, xBase), using super fast build times on systems running at 10 Mhz, within 640 KB.
I built a TUI application for MS-DOS (well, DOSBox) recently, just using the few functions in MSC 5.1's included graphics library (plus a few simple BIOS calls) and what a joy compared to web interfaces or any GUI library I have used. Having a fixed screen size and known, limited, character set is at least developer-friendly. Of course there existed more advanced libraries as well, but for a simple TUI just a few functions can go a long way.
