people 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.
I must admit I'd not met the T-11. I stand corrected.
As for the F-11, hadn't I just agreed with Tony that a chipset like the
F-11 was a microprocessor?
