Hi, I just picked up a Sun 3/80 chassis from the local
university surplus...
Isn't that the Sun3 in a SPARC1 chassis? Neat find.
I'll consult the various faq's on the web
about the NVRAM, and maybe
drill some mounting holes for a hard drive (didn't come with a hd carrier, and
I can't find any).
See if you can find some SPARC1/SPARC2. I also used some washers and
screws for my first SPARC1 before I found some drive sleds.
I don't know much about the Sun 3 series though -
most of what I see from a
google search is about the 3/50 and 3/60's. Is the 3/80 an ignored bastard
child from sun? A 68030 in a pizzabox, not a classic Sun 3, but not a Sparc
either?
There were a lot of 3/50s and 3/60s shipped. I think the 3/80 was a
last stab for customers with a large investment in 68K
hardware/software, but with an upgrade path to the new SPARC line. As
a result, I don't think many 3/80s were shipped compared to what came
before and what came after.
I don't know if 3/80s use the same 48T02s that were used in sun4c
machines, but it's likely. I'm not sure if they are still available
new, but with some careful surgery, it's possible to disconnect the
old battery and add taps for a new one. Do not remove the entire top,
though... there's at least a crystal and perhaps a couple passive
components attached at the other end.
