Books on programming the 8 will tell you pretty much what you need to know about the 9. The assembler on the 9, on the Dectape based OS, was retrofitted from the PDP-15. The manuals were the same.

Except, of course, for the word size, since the 8 had 12-bit words and the 9 had 18-bit words. And except for the instruction set, which was different... > The assembler on the 9, on the Dectape based OS, was retrofitted > from the PDP-15. The manuals were the same. Well, since the PDP-15 came out as a successor to the PDP-9, either the PDP-9 didn't have an assembler until the PDP-15 came out or the PDP-15 assembler was made out of the PDP-9 assembler (a little more likely). (BTW, I was very surprised when I read between the lines of some PDP-9 book and found out that the PDP-9 was microprogrammed...) Guy Harris {seismo,ihnp4,allegra}!rlgvax!guy
