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

[Alan Perry]

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).
