Paul,
Thanks for your insights. I found some useful background info here:
http://keemiarelva.tehas.ee/asjad/telecomi%20plaat/Kompuuterelektroonika/
These docs are in English, written (or at least compiled) in the early 80's.
I'd be curious if anyone knows the original source for them. In any case,
see the top of page 9-11 in the file 14091_ch9.pdf.
It says "In addition to lateral parity, many units also use a longitudinal
parity check." That seems to imply that some didn't.
????
best regards,
