I have one of these 80 column cards, I've lost the user manual and google can't find it anywhere, so I need a copy, has anybody got one please?
From Wikipedia <https://en.wikipedia.org/wiki/Andy_Hertzfeld>:
"He was hired by Apple Computer as a systems programmer in 1979 and developed the Apple SilenType printer firmware and wrote the firmware for the Sup'R'Terminal, the first 80-column card for the Apple II."
Based on this, I think you are looking for the "APPLE LANGUAGE SYSTEM - Intstallation and Operating Manual" (a small pamphlet).
If you still cannot find yours (or a PDF of it), reply to me privately, and I will scan it into a PDF for you.
