insist a microprocessor is one chip only. 
 So I notice.  But by that definition _none_ of the micro PDPs were true
 microprocessors, or at least none up until the 73.  The Micro J-11
 processor in the 73 was implemented as two chips on a large ceramic
 carrier.  Was this also the case with later J-11s? 
Yes, it is.  But if you allow a J-11 as a microprocessor, you must also
allow the F-11 (as in 11/23, 11/24) since it too has the complete CPU on
one (40-pin) carrier.  The other devices that make up the chipset are truly
optional.  You'd also need to allow the T-11 processor.
