The crystal oscillator may or may not be OK, but low voltage can still
cause the surrounding logic in the NVRAM chip to malfunction, or an IO
signal from low to high voltage to be interpreted as the wrong logic
level. Remember -- the claimed problem is not that the clock is slow
but that the t
My understanding is that the time is read from the NVRAM chip only once
when booting, then the time is updated by the kernel clock() function by
interrupt 10 while running.
High interrupt rates could cause the clock interrupt to be missed,
slowing time. A lot of serial activity could cause it.

You can get replacement NVRAMs from here

I have hundreds of still in production Netra AX1105's and this is the only
source I've found for Sun NVRAM.
They come pre-programmed with MAC/Host ID so if you need the existing
config you'll have to program it yoursel
Hello Jim,
We've got a few of these old beasts around; the last of 'em still anxiously
awaiting its, uhhh... 'Retirement Party'.
Seems to me we had to replace a battery on at least one of these at some point,
but don't think it was the CR2032 'button' type, as I recall. Happy to send you
some

Don't bother. There is lots of stuff for E450s right here in Europe.

Sad, nice boxes, they were. Afaik some were refitted into zfs nases, maybe
keeping only the stylish case with different mobo's.

You'll need to copy all that down, particularly the CPU ID if the software is
locked to a particular host. That should be

You should make it perfectly clear to them that a backup you can't
restore is a backup you don't have.
