Great news, Dave. Didn't know that Samsung was still selling those 
models -- W6GJB and I bought a bunch of them 4-5 years ago, and thought 
they had been discontinued. I'm running them on my living room computer, 
my wife's computer, the shack computer, and on two P3/SVGAs. The ones in 
the shack are on a 12V 100Ah SLA battery, the others are run from much 
smaller 12V SLAs. The SLA in the shack is floated from a re-purposed 
Thinkpad PSU through a Genasun MPPT charge regulator for solar systems; 
the ones in the house from much smaller linear supplies. All of the 
computers are Thinkpads of various vintages.
