I think there were many more variants. Commercial and scientific, sure, but
both of them in many variants as you travel from one computer manufacturer to
another. The CDC 6000 series had their own very odd character set; the Dutch
Electrologica had at least a couple of codes including one specifically for
ALGOL 60; DEC had a whole pile of choices -- and so on.
