Building a keyboard from an old typewriter

I was day dreaming today of doing the opposite: attaching a modern mechanical keyboard to some sort of printing device. I figure an electric typewriter like this would be ideal for this kind of project. A dot matrix printer might be more hackable...

You mean something like?:

ddevault did something like this pretty recently: https://drewdevault.com/2019/10/30/Line-printer-shell-hack.h...

A daisy wheel or type-ball printer would look better. Many of them even had serial interfaces.

Old-school IBM daisywheels actually have an exposed port for controlling them remotely. You can drive one with an Arduino and with sufficient lateral thinking you can draw graphics by microstepping and printing full stops. The protocol's funky, though, and the ribbons aren't cheap.

I was hoping for something that looks like the Brazil Movie computers... http://www.tronola.com/assets/images/Brazil_movie_computer_2...

why not put it in a different case
