I gave my typewriter computer some big upgrades
I've made some progress turning my typewriter into a computer, and now I can print much larger ASCII art using it! I added software flow control, and added code to process escape sequences to use the typewriter's formatting features.
I got a Brother AX-25 electronic typewriter from the 80s a few weeks ago, and I've been working on modernizing it with an Arduino and a Raspberry Pi. The Arduino controls two multiplexers that emulate the typewriter's keyboard, and the Arduino is hooked up to a Raspberry Pi over serial. This lets me use my typewriter as a Linux terminal, or as a teletype.
