CDC6000 or was it the Interdata 8/32 used a nine bit char.
Funny thing about all this. I see focus on the char, int and longs and
pointers with little regard to is the machine Von or Harvard and other
considerations such as base machine registers, addressing modes and
conditional branch capabilities. All that is needed is enough bits
to do the task(s) desired. There is a point where standard C doesnt
fit well enough to justify it. That doesnt negate a subset however.
