sun model 47. code 4/40 does it have the nvram with battery?

[Alan Perry]

There is only room for drives in the top half of the chassis.  The PSU 
and an assembly that holds the drives fills the top half. A 3.5" 
half-height drive fits in one side of the assembly and a 3.5" floppy 
drive fits in the other. The PSU cables go from the rear to the front of 
that side of the chassis, below the FDD (when the chassis is closed).

I did an exhibit on Sun lunchbox systems, including the IPC (4/40), for 
PNW VCF earlier this year. I looked for press kits, posters, etc. to use 
in the exhibit, but could only find text files. I know people who worked 
at Sun on the development of those early SPARCstations and none of them 
had any of that kind of material.

I had an audio cassette "Introducing the IPC" for Sun sales. I donated 
it to CHM this year (but I ripped the audio before I sent it to them).

I  do remember   lusting  after  one of these   1U  COBALT  servers when they  were  current didn't  have anything in  the  budget  back then  though  for  one.  I  have  been  told  SUN  eventually ended up  owning COBALT.

The chassis splits in the vertical middle in a, if looking at the chassis, fairly obvious place. Because of the cables that run from the top to bottom, it effectively hinges at the front of the chassis. There a couple buttons on the side to release and sometimes a security cable bit to remove (phillips screw).

After that will likely be the HDD that needs work. Almost all of my HDDs that originally shipped with lunchbox systems up to the 424 meg (ST1480N) have died. The price for working 50-pin SCSI HDDs are at a point that SD2SCSI parts make more sense (unless you want to exhibit them as they originally ran).
