True. If memory serves.....
Some Teletype units ran at BAUD Rates lower than 75 even
Correct me if I'm wrong.......
It's been a long time since I've seen a Teletype.
It's been so long ( circa 1978 ) since I cracked a technical book on teletypes ( I was into shortwave listening back then, and intercepting radioteletype (RTTY) feeds ) that the exact relation to baud rates, character per second, etc., is hazy, but standard speeds were 60, 66, 75, and 100 words-per-minute ( WPM ). That assumed some arbitrary average word length, and was based on a 5-bit character, which was standard teletype practice.
The baud rate is related, and numerically close to WPM, but not exactly the same thing.
60 WPM was the old US standard, 66 WPM was European, and 100 WPM was used by the armed forces a lot... I actually had a surplus Kleinscmidt portable tty that had change gears for all speeds- it came in a neat magnesium, watertight carrying case. Kind of wish I'd held on to the dern thing, now!
