Thanks for the info to get it open! when back at the office shall do that.. there may be drives in 2 places - on board and the off board one. Always interesting to explore something one has only read about!
Along the same line of UNIX stuff we have a COBALT 1U Pretty blue sever and a COBALT CUBE. 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.
As will all that we have we are looking for any ad slicks press kits posters, wild artwork for the Sun $/40, and the 2 COBALT machines..

Yes. It is next to floppy in the upper half of the chassis. There is a 50-pin (IDC connectors) ribbon cable that goes down to system board at the bottom of the lower half of the chassis. 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).

Hi Alan - The hard drive is same size cabinet.... with I guess a SCSSI cable. I will have to look at it further... wonder if starting it out on a variac would help the capacitors like I do with the old radio sets here in the museum ed#

Well, as I said, in my experience, the NVRAMs that you can buy new from Mouser work good enough. And the mod to the original battery isn't that hard to make.
In my experience with IPCs, the bigger problem is the power supplies. If the PS on the IPC that you have now doesn't need to be re'capped now, it will need it soon. 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).

A 4/40 is a SPARCstation IPC. It used a M48T02 NVRAM for the IDPROM.
Yes, one with the dreaded battery.
