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.
