[GreenKeys] Slashed O or Zero? RE: 120vdc connectors - opinions?

[Dave Wade]

Folks,

 Robert, that really helps me clarify things. I was pretty sure both worlds
exist, because I remember having this conversation on a Geography Field trip
to Swanage and the Isle of Purbeck (which is not an Island) over 40 years
ago. 
 Whilst I don't remember the specifics, I remember that one of the people
running the course was involved in computing on an ICL machine at Hatfield
Polytechnic and I was using an old IBM 1620, posting my coding forms off in
the post.
 It seemed though as if we lived in different worlds of computing. She (I
remember it was a lady) used paper tape but we used cards, and one of us
slashed the letter and the other the number.....
..  but I can't remember which of use slashed which! I do think they had
ASR33's at Hatfield....

I see this has come up before..
