Silliness with Serial Console


-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hello everyone (or noone),

I have a 3/60 that I'm trying to get a serial console on. I made sure
that my cable would work on my SS10, and it did, but I get nothing on
the 3/60. I played with flow control and the null adapter too, no
dice. 

I have the LED opposite the power supply on when I power it up. I
know that this is a problem, but I figured with the DIAG switch
flipped I'd at least get some output. I believe this LED means a bad
PROM. 

Also, if anyone has a 3/80 or higher Sun3x machine they'd like to get
rid of, let me know. 

Thanks!

Sure you wouldn't like a nice Sun 3/50 with 12 megs of memory?

Or a 3/60 with a dead PSU (I suspect it exploded because it wasn't
actually designed for 240v - even though it was shipped to the uk).

Aren't the 3/50 and 3/60 PSU's compatible? My fan is extremely loud,
probably beeds cleaning.

Actually, I'd probably like it either way.

Hrm... So, what is a possible course of action? Should I investigate
getting a new PROM? Is there a good source of troubleshooting info
for Sun3's that I'm missing?

Also, How long does it take to perform these tests? Maybe I'm not
giving it long enough, it hangs at that test for about a minute. And
shouldn't I still get at least some output on the serial line?
Something that says "Hey, this test failed" like I believe Sun4's do?

Thanks again for all your help.

What error did you actually get?
If you got error during PROM check sum test, it might be worth
to replace PROM. But if there is some actual hardware problem,
I'm afraid it isn't easy to fix.

IIRC, actually the DIAG tests will take about a minite.
(I didn't try it with serial console, though)

The SUN hardware reference
http://www.sunhelp.org/faq/sunref3.html
says "self-test messages are sent to serial port A" (in 501-1205 entry):

> If you want the machine to boot normally, set the diagnostics

> power up the system, set the switch to the "DIAG" position. If

I con't seem to find a clear, concise reference on which LED is
which. The one on my Box that lights up is the one closest to the
Keyboard connector, is that 7 or 0? If it's 7, then I guess it just
means error found... but if it's 0 it means the PROM CHECKSUM thing.

Thanks!

I have a 3/60. It says:

The pattern is shown right to left, as it appears on the LEDs.

So, in that case, if I were looking at the LEDs, then the right one
would be bit '0' in your diagram. Therefore, the LED that is actually
on in my case if the '7' bit, which simply means tests have found an
error. That's not terribly descriptive, Sun. :)

These LEDs flash within a second though, I see bit 0 light up, then
bit 1, etc. Until it reaches bit 7, where it stays. Nothing ever
comes in on the serial line, even with the Diag switch, and the LED's
status never changes. 

I'm beginning to think that this guy has bit the dust.
