Do they have the yellow-on-blue syntax highlighting trademarked or something? I've looked for vim and vscode color schemes to match the original turbo c++ but to no avail. I remember borland builder had a setting to switch back to it.
That's a nice color scheme, but what really made those text-mode IDE's intuitive was the TUI widgets and support for multiple views. Probably easier to do in neovim than plain old vi/vim of course. With modern devtooling support as found in neovim you could also have inline help, which was also very useful in those older environments.
Probably no one else saw interest to do it? I do remember seeing something similar for emacs.
