I think I've seen the SAIL keyboard before but only just noticed where they put the 0 key! I've never seen a keyboard put it over there before!
Good eye! I saw it only a few times, with the PLATO computer, modern keyboards in Hungary, and CDC 6600.pic.twitter.com/X2nO4aGCg7
I was trying to figure out if it was a bit-paired keyboard or not. :-)
I believe they all could put zero in front because they didn’t have to worry about bit-pairing?
(Except I don’t know much about the Hungarian one.)

Or it was programmer-centric where 0 comes before 1. Early typewriters used an O for a zero (my Dad had one); later ones put the 0 after the 9.
My theory is that we ended up with 0 on the right because typewriters got 0 decades before they got 1. And putting 0 on the left without 1 seems… weird?pic.twitter.com/qwjvp4kd7O
That's very very likely! I wasn't aware typewriters added 0 before they added 1. (I wish Dad still had his ancient typewriter, but he gave it away decades ago.)
I don’t think I really have a good answer why 0 was added first. Let me ask around. (It definitely was a gradient depending on manufacturer and country, and there was some weird situations like these, too.)pic.twitter.com/0UiTWVlIkV
(My favourite example is here, where we were still deciding whether it’s O or 0 that needed extra ornamentation!)pic.twitter.com/fGPspG0Or8
I vaguely remember reports of problems using a slashed 0 in some Scandinavian countries because it collided with a real letter: Ø.
