I have been going to our HP 21MX paper tapes that come with a M-series
system that we received many years ago:

I tried to check if they already were available online somewhere but didn't
find them when doing quick checks on random tape part numbers in the spread
sheet. Maybe they are and then I don't need to bother reading them.
Otherwise I will try to read them if there are interest and when I get time.
