[comp.sys.mac] More info in XT-2190 problem

) (09/29/88)

Hi,

This is a followup on my XT-2190 problem.  If you recall, I have an Apple
80mb and an XT-2190 (by way of an Adaptech 4070 controller), both
connected to the internal SCSI bus in a Mac II.

Well, it broke.  As soon as the XT-2190 come ready, my Mac plays 4 chords
each higher in note than the previous, then the screen goes dark blue and
hangs.

Well, I did some troubleshooting tonight.

1) Only Apple 80mb connected   -   it works fine.  This means I did not
	fry my Mac SCSI port...

2) Only Adaptech/XT-2190 connected, I get the 4 chords and a SAD MAC with
	0000000F
	00000003

	on it and a dark blue screen.

3) Only the Adaptech connected, ie,  the XT-2190 disconnected from the Adaptech,
	but the Adaptech connected to the bus, the Apple 80mb boots. SCSI bus
	CDEV by Paul Mercer sees both devices.

So it looks like the drive is at fault.....

I am not willing to dismiss it as a faulty drive that quickly.  On powerup, it
DOES do the 18 zone reads the Adaptech tells it to do for Bad block replacement
and it DOES pass the Adaptech diagnostics.

APPLE,  please tell me what the error chord I describe means?
APPLE,  what are the Sad Mac errors I describe above.
