'adb' is quite late. We had it on the PWB1 (V6 enhanced, basically) system at

Yeah, it's in the PWB1 source tree. FWIW: Bourne wrote it ( and it is written in his unique 'BourneGOL' C macro dialect) which (I think) makes it a PITA to modify. Later UCB versions for the Vax removed Steve's macros. So it has some sorts of roots in Research, and most of the world did not get to see it until V7 appeared.

(Every time I run across people who think V7 is early, I go into 'get off my lawn' mode.)

Amen.
