Doohickey type music.

On the eight day of Christmas, my true love gave to me…

That's such a bad title for this post.

This is amazing. Thank you, OP.

Unreal, thanks for this.

Phenomenal.

"this is the creation of a man with nothing to live for" is one of the best lines ever written.

That's right; "accidentals" in English are the notes on the staff with a sharp or flat.

That’s really ingenious, and it must have been useful while traveling, even if I imagine the sound wasn’t the best. I play the piano, so I really get the pain of not being able to take your big instrument with you.

Edit:

black-stained accidentals covered with rosewood plates

“Accidentals” refers to the “black” keys, right? It’s the first time I see this word applied to keys, is that common in English?

Compare the later IBM 7094, famously used to sing Daisy Bell, as darkly referenced in 2001: A Space Odyssey.

I can't find the longer demo recording. Right before the song, they did the soliloquy from Hamlet. "To be, or not to be - that is the question. Whether 'tis nobler in the mind to suffer the slings and arrows of outrageous fortune, or to take arms against a sea of troubles, and by opposing, end them. To die, to sleep..." And then pointedly not suggesting that a computer can dream.

Very neat

Thank you for posting this, I loved seeing this instrument in action.

Somebody show this to lemmygrad!

It's the people's instrument!

Do you get a complimentary copy of "Das Kapital", when you buy one of those?
