Subj:	Audio PCB self test

Ed --

Jed's self test does not report on the status of the SA II 
audio PCB. You need to get with him so he can change his self 
test program to look for the following info. from the audio 
bd.

Below are the bits that RPM set when the following test(s) fails:

	P1BAD = 080		;80 = 1st (4000) PROM bad
	P2BAD = 040		;40 = 2nd (8000) PROM bad
	P3BAD = 020		;20 = 3rd (C000) PROM bad
	R1BAD = 010		;10 = 1st (0000) RAM bad
	R2BAD = 008		;08 = 2nd (0800) RAM bad
	IRBAD = 004		;04 = IRQs not present
	YMBAD = 002		;02 = YAMAHA timed out
	MLBAD = 001		;01 = mainline not running


This byte is reported to the master when S_STAT is called.
