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).

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).

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.
