Ah, right. That was on my table too, but I didn't understand it.
All octal from here on.
CDC had several different character sets, most called BCD. They were
unlike Fieldata, which in fact bore some resemblance to ASCII (letters
starting @ABC.. from 0 (or 40 in ASCII), digits starting at 60, ...)
Wikipedia mentions one called "CDC display code" that went :ABC..., then
the digits followed after Z. Also, according to Wikipedia, Fieldata was a seven-bit
code
Yes, I saw that too. As used on the big UNIVACs, only the low-order 6
bits were used. I note that the upper 64 characters include control
characters.
with A at 006 (putting Z at 037) it wasn't
ASCII-like at all, except
for having the letters in a continuous run.
Hmm. Somewhere I read a different version where the A followed
directly after the @. I stand corrected.
