Either I am very young or you are very old, because ANYTHING with a fixed 80 column screen is definitely retro. This is a weird thing to gatekeep.

What commonly used UNIX terminals had less than 80 columns? VT100 had 80 columns, IBM PCs had 80 columns. I remember some 8 bit computers having text modes where you could choose to display less columns in return for getting more colors, but those computers never ran UNIX and getting on usenet was surely a pipe dream.

I agree, any terminal I ever used to access a shared unix host had 80 columns. Typically a VT100 or ADM-3a or something like that.

TRS-80, TI-99, Commodore, Apple etc. home computers had 32, 40, maybe 64 columns and you could get terminal emulator programs for them but most people would use them for CompuServ or America Online, or maybe BBS logins. I think I tried using my TI-99 terminal emulator with a unix host and it wasn't very successful. The host had no idea what my terminal was and operated in a very limited "dumb tty" mode.

Eh, to do it properly, 40 cols and less would require adjusting the whole layout and I just want to keep the code simple. I'm also not sure if the code would be fast enough to run on so old machines, I mean it's Python and not optimized at all. But feel free to fork and tinker if you're interested, at this point it's not really far off.
