Original Teletype machines ran at 45.45 baud.
I remember labels on Creed machines saying "50Bd".
I had a Creed 7B 60 years ago, I used it for RTTY. It had two
governers, one for 45.45 Bd, the other for 50Bd. They had white strobe
marks on the circumference to set the speed accurately.
Hmmm ... presumably the strobe marks were for use with a fluorescent
light ... driven from AC mains frequency? Did they have different marks
for 50Hz versus 60Hz mains?
No, that wouldn’t work, you would need entirely different gearing for the
strobe wheel ...
