First of all I just wanted to say that Gary is my old "big toe" at college.
Gave me my first intro to UNIX - "Don't mess with the software".
I think I ended up with a C average.  Oh well, a few beers at the local pub
and all was well.  Hope things are doing good besides your 170E Gary.

The best NVRAM faq follows.  Has links to NVRAM chips for $20.
Your not getting ANY errors in your massages files?
Have you changed the cooling fan yet and given the MB a good air wash?

The clock on my Sun has stopped working. When I turn off the machine it
loses track of the time and/or complains about invalid TOD when I turn it
on. How do I get my clock to keep time when the system is off? (Replace
chip)

WARNING: TOD clock not initialized-- CHECK AND RESET THE DATE!
========================================================-===== This message
indicates that the Time Of Day (TOD) clock reads zero, so its time is the
beginning of the UNIX epoch: midnight 31 December 1969. On a brand-new
system, the manufacturer might have neglected to initialize the system
clock. On older systems it is more likely that the rechargeable battery has
run out and requires replacement. First replace the battery according to the
manufacturer's instructions. Then become superuser and use the date(1)
command to set the time and date. On SPARC systems the clock is powered by
the same battery as the NVRAM, so a dead battery also causes loss of the
machine's Ethernet address and host ID, which are more serious problems for
networked systems.
