I picked up a nice looking 5140 today, even has a very nice IBM matching carrying case. The wall wart (ac adapter) though looks wrong, its IBM, but its small ala 200 MA (I gotta read the numbers, sorry, but I wanted to post about my new toy right away). Anybody have details on the AC adapter, i know its model 6820822 from a dealer ad, but naturally they don't mention the output voltage etc. Looks like a brick sized unit.
