[GreenKeys] M33 "O" (oh) vs "0" (zero)

[Chris Elmquist]

My latest M33 rescue was rebadged by Anderson-Jacobsen and has an acoustic
coupler installed in the right half above the power supply.

Interestingly, the keyboard has a slashed O (oh) between the "I" and the
"P" and then the zero is unslashed.  This is of course heresy for those
of us that live in the 10th call district where we grew up knowing that
zero was always slashed and oh never was :-)

The machien prints the slashed O when it should print an oh and it prints
the unslashed zero when it should print zero... so apparently the type
wheel is correct for this configuration of keyboard.

Was this a normal configuration at some point?  Or this is something
that Anderson-Jacobsen might have done custom?

My older M33 is not configured this way.  On it, the zero is slashed
and the oh isn't.  This older unit also has an "ALT MODE" key where the
newer one has "ESCAPE".

Some of my research shows that there was a pre-ASCII 7-bit keyboard circa
maybe 1962 that had the ALT MODE and then there was an ASCII conforming
keyboard around 1968 that introduced the ESCAPE key and became fully
ASCII compliant.   However it seems funny to me that the slashed O and
unslashed zero would have been in that configuration then too.
