! I've got an SS1 with a dead NVRAM chip. From the FAQs I've read, it's
! trivial to set the MAC address after the chip dies and it's set to
! FF:FF:FF:FF:FF:FF. Providing I use the Sun "standard" of
! 08:00:20 as the
! first three bytes of the MAC address, is there any real issue with me
! choosing a random value for the last three bytes?

..it talks about how to change the MAC address, as well as changing the
battery in the NVRAM chip. I haven't tried resetting the MAC addresses on my
2 SparcStation 1+ and SparcStation 2 yet, haven't had the chance.
BTW, talking about collections, besides the 3 Sparcs, I also have...
- Sun SparcStation LX (w/ 20" monitor, and optical mouse)
- DEC VaxStation 3100 M38 (32MB RAM)
- DEC 3000/400 (with the 20" color monitor)
- AlphaStation 200 4/100 (dead power supply, and I think the mainboard might
be dead too.)
- various 68k Macs (LCII, LCIII, SE30, SE HDFD, Classic, IIci) some for
sale/trade
- 2 HP ScanJet flatbeds (for sale/trade)
The Macs are in the basement at home, and the big stuff is in my office at
work :-)

Not unless you have some licensed software locked to a particular ID, no.
The only possible problem is if you guess a number that matches another
Sun on your network and you'll have all sorts of fun.

I've done it for every sun4c machine I've ever had. At one point, I
had a regular expression to grep out six letter words from /usr/dict/words
with a-f and perhaps i and o. There are a couple more than c0ffee, but
that's the canonical one from the NVRAM FAQ.

On Solaris 7 (OT, I know) the little Perl snippet below finds 14 matching
words, on a current Linux system I get 23 hits.
Perl snippet:
#!/usr/bin/perl
while ( $line = <STDIN> ) {
if ( $line =~ /^[a-fio]{6}$/ ) {
print $line;
}
}
Regards,
Alex.
