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

[Alan Perry]

A company called RDI made the Britelite and Powerlite laptops. They 
eventually merged with Tadpole, which made its own SPARC laptops 
(SPARCbooks). As someone else mentioned, there were different Britelite 
models based on the various Sun lunchbox system boards. When I had my 
Britelite IPX on display on VCF, someone told me that they recognized 
the case as something used in another laptop.

Sun never made their own laptop, but they made a portable called the 
SPARCstation Voyager.
