  Also, while looking for the vi cards, I turned up two wonderful artifacts
  that I'll try to get scanned and added to TUHS at some point. When you
  purchased V7 from AT&T, you got one copy of the printed docs and a small
  "purple/red" 9"x3.5" flip-binding reference card that Lorinda Cherry
  compiled. Also, when DEC released V7M-11, they printed a small flip-binding
  8"x4" reference called the "programmers guide" [AA-X7978-1C]—which is
  similar but different.

And Matt G. wrote this in Jan 2026:
  The references in the end date this to the Sixth Edition.  There is a
  blacked-out bit in the TROFF User's Manual reference, I can't quite make
  it out, it was in previous generations of whatever scan this came from
  but I can make out a 127 and a 4 I believe, it's probably a crossed out
  memorandum number.

An OCR version of this document is also provided.
This was produced via Archive.org's derivation process
and is of diminished visual quality.

UNIX_Reference_Card_Second_Edition_by_L.L.Cherry.pdf

and

UNIX_System_Quick_Guide
-----------------------

Both of these scans were provided by Mary Ann Horton.
The Second Edition of the UNIX Reference Card in particular
involved a series of section markers, each offset from the last,
allowing for quick selection of the pages needed.
This is explained further in the scan.

UNIX_Reference_Guide_Release_4.0.pdf
------------------------------------

This is another such reference card distributed by USG in
the era of UNIX Release 4.0.  This scan was performed by
Matt G. from an original provided by Arnold Robbins.
