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).
