P-4 or P-6?

[Ken Kelly]

Gothcha,
	This really says that P6 means Processor # 6 or the HC11F1.
There are really major architecture differences going from
93 to 94 in the LT1 PCM's, but they do keep that processor,
only double them up!!

	I haven't played with the 97 PCM's. 93-96 is all I have
looked at.
