As pointed out, no model 69, though I do recall a 65. And I also
recall that list posted on the front panel of either our 360/30 or 40.
Let's see, it also had RSC=read and shred card, among maybe one or two
dozen other mnemonics. But I don't have a copy.
You think you could scan your copy and post a pdf somewheres???

Before we got a 360/30 (at NYU's School of Commerce Academic
Computing Center) we had a 1620. Maybe the list existed then,
but it definitely didn't appear at ACC until circa 1968 and
the 360/30 or 40.
