On John Savard's site he has a page on punched cards and card codes. By any
chance is the representation of the card code correct for the full
eight-bit spectrum?

Also perhaps this is somewhat off topic, but were there ever card punches
on DEC machines? I know of the various readers, but not punches except I
think for the '10.
