If it really is a 4/110, it has a switch labelled "NORM/DIAG" on the
front panel. Power down, switch to "DIAG" and try again. Be prepared
to wait half an hour or so for the extended self test to complete,
depending on how much RAM it has.

You _are_ using a nullmodem cable?

Half an hour? Jeez and I thought my old MicroVAX took ages to start! :-)
Yes it does have a NORM/DIAG. Sorry I didn't mention it. I've tired it in
both modes but haven't waited half an hour! Isn't it supposed to output the
diags to the console when testing?

Sure am! Just a simple RS232 Cable with a null modem adapter on one end.
You know when I was getting my VAX up and running a couple of years ago, it
took me days to actually realize that the console serial connector was DCE
and not DTE as was to be expected! :-)

Thanks for the reply!

This is a followup to my followup! :-)
I left the machine on for about half and hour and when I returned it, the
DIAG LEDS displayed the following:
(The left bit is the top LED on the VME card)

01001000

Unfortunantly this is meaningless to me as I can't get the LED specs for
the 4/110.

Can ANYBODY help???

Best Regards,

Chris Fletcher.

The manual says that test 0x12 tests the "parity circuit".

Ahhh so the leftmost bit is actually the Least significant Bit. Hmmm funny
way to have it! :)

When you say it tests the parity circuit, i assume you mean the nineth bits
in each SIMM. I have placed all parity RAM in banks one and two and set the 
appropriate jumpers however the SIMMS are not 501-1466 SIMMS. They are all
9 chip however. Is there any difference between 501-1466 SIMMS and normal
1MB 30PIN 70ns 9Chip SIMMS?

I assume that if it is staying on test 0x12 then that's where an error is
occuring. (Is this the case?) Why isn't it outputting the error to TTYA?
(Or is it like the first few tests of the POST on a PC before the display
is initialized?)

I guess this means I'm going to have to sort through bloody SIMMS one by one!
:( Now that sounds like about as much fun as itching powder in your wetsuit!

Thanks muchly for your reply, it has been of great help. If you do have the
time, I'm sure many people would be grateful if you could send the LED error
codes to the Sun Reference Manual on the sun help webpage. :)

Chris Fletcher.

	when the CPU is in the slot, the topmost LED is the
	most significant bit - this error is test 0x8, which
	tests the TOD clock interrupt.  Bit 6 on says that
	an exception class error was detected.


	Serial port A is closest to be bottom, next to the
	SCSI connector - you need a null modem to a 9600 bps
	terminal or pc with terminal emulator software.  The
	diagnostic routines should be pumping out yards of
	test gunge to the serial port (which should be visible
	unless the baud rate has been changed in the NVRAM).
