It is my belief that the Series II microcode listing was a part of the standard manual set that you got with an HP 3000 Series II.  We had one at the high school (where the 3000 started out as a Series II and was upgraded in its chassis to a Series III).  Also that the Series III’s microcode listing was not part of the Series III’s standard manual set.  We didn’t get an update for it at the high school either.
