Any old timers around who worked with 80 column IBM punch card

I saw that too, but I don't know any one with access.

Thanks for checking I hope you find something useful.

I have some punched cards coming from EBay. I have some unpunched cards that I have taken some measurements from.

My guess is that the dimensions will be simple numbers like 0.05 vs 0.048 or the like.

Thanks in advance for any help you can provide

My employer's subscription covers lots of specs and ANSI specs, but their subscription doesn't cover this one. :(

Also, the document is now known as
INCITS 21-1967 (S2017); and is available as a pdf through ANSI for $60.
