[edit] And now you can hear the bell(s)! Actually a whole episode on it: https://youtu.be/b2QPy-igBLA

Some commenters requested that we use our restored vintage 1930 Model 15 Teletype as a terminal for Linux. Hooking up a 5-bit Baudot mechanical contraption to a modern OS, even one that is terminal friendly, is not without some challenges: adapting to the non-standard high voltage 60 mA current loop, interfacing ASCII to the much smaller and different Baudot encoding, working in all caps, dealing with Baudot FIGS and LTRS modes, and making sure the computer doesn't overrun the pokey 45.5 bauds connection. But hey, Unix was developed on (much more modern 8-bit) teletypes, so that should still work, shouldn't it?

The bell can now be heard playing the Teletype March: https://youtu.be/b2QPy-igBLA

I realized after making the video that original circuit should be credited to TeleTweety (Eric Volpe), who has all kinds of fantastic teletypes running twitter and other things at his home:
