When I took a closer look at the Bell Labs CARDIAC manual from my prior blog post, I caught a diagram labeled, "Fig. No. 5. Flow chart for repairing a flat tire.", that would (hopefully) never fly today, especially in a document intended for encouraging young (middle/high school) students to consider pursuing computer science:
p.6, An Instruction Manual for CARDIAC, David Hagelbarger and Saul Fingerman, (C) 1968 Bell Telephone Laboratories
Mind you, this was originally printed in 1968, when people (obviously) just didn't consider such gender issues.
