I have a chart of paper tape hole patterns for all 128

them 1-8) as the

hole on the 3-hole side, with the bits in order 0 to 7
(or 1 to 8).
However, one question, this chart shows the high-order bit (parity
bit)
punched for every character, no exceptions. Was that
a standard
convention
in sending ascii files to paper tape?
It was for DEC, at least with PDP-8s. I don't know about anyone else.
