I just acquired what I believe to be an early 'green card'. It's actually a white booklet, GX20-1727-5, 20 pages (back cover is page 20). Title is IBM System/360 Reference Card - System/360 Model 20
I remember hearing/reading some trivia that the original 'green card' was white. Looks like the same format as more recent cards. List of instructions much shorter that the GX20-1703 cards. Can anyone confirm/deny that this is a predecessor to the more familiar foldout cards GX20-1703 series?
