I bought the original spec MIL-STD-1815 10-December-1980 back in 1980 or so, but it didn't survive a purge I made when moving. A couple years ago I went looking for it. It's not online anywhere, but I found an old library copy for sale and snapped it up. It's green, and I don't have any of the other specs.

I'm sad I also purged my DECSystem-10 "Orange Book". I've never been able to find a replacement anywhere.

Do you remember if the nickname was "Orange Book" or was it "phone book"? I didn't see the former when searching for more information, but the latter was referenced here [0].

If it's actually "phone book", then [1] seems promising.

It looks like the "Assembly Language Handbook" in the first reference. It was a very thick book, printed on very thin paper like a phone book. I clearly remember it as "Orange Book", after all, it is orange, but that just might have been Caltech vernacular. (Caltech had many local words unheard off campus.)

A marvelous find, thanks! I'm glad they haven't all vanished. I'd still like a scan pdf!

Hmm, you may be in luck. That one looks like it's in the parent directory of the second link: http://www.bitsavers.org/pdf/dec/pdp10/TOPS10/1973_Assembly_...

Sweet! Nice to see that manual again!
