While we're being nostalgic, VDE, a WordStar clone, was another miracle of tiny code. I still run it now and then in a DOSEMU emulator on Linux.
I've looked into it in the past; does it work like WINE, or is it basically Dosbox with better hardware and filesystem access?
I've also seen Dosemu2[1], because apparently the original was no longer under development, so I'm a bit concerned at how well it works nowadays.
