I know that ;)
Both connectors on that cable are IDC connectors.

Well, my model 2 printer cable uses one of these, as does quite a number
of my Apple II machines. I have tons of brand new 36 pin connectors in a
box somewhere that I got as part of a bulk deal. They seem to be very
common for printer cables for Tandy and Apply computers made around
1983-1988. (I don't remember if the box I have is full of male or female
36 pin connectors, however.)

Well, I'm speaking based on the one I currently own, which certainly does
have IDC connectors on each end of the ribbon cable.
