I went ahead and ftp'ed the Win98 install disk onto my Stylistic. It took me a while to figure out how to get the install to work using a non-upgrade CD, but eventually I got it installed. I picked up a Belden BusPort USB PC Card, which is expensive, but has a very thin connector (required because my other PC Card, a Sierra Aircard 350 CDPD, has an antenna directly attached).
I also picked up a 4500 mAH battery on Ebay, and a hazardous environment case. I had to make some holes in the case for the USB dongle and antenna to stick out. The case has a foam rubber lining, giving a lot of protection to the already mighty hardy Stylistic, and has a see-through plastic panel over the LCD so you can operate it inside the case.
So now I've got a cool portable wireless webcam that runs for over 3 hours sending out an image once every two minutes :)
My last design was based on a Ricoh Magio, which while being physically smaller than the Stylistic, it was made of thin plastic, and got beaten up very badly (making it impossible to hot-swap the batteries), and the batteries only lasted about 1.5 hours. Then I spilled lemonade on it...the eraser-head style mouse burnt out. We used a PS/2 mouse, but we kept the Magio in a loose-fitting bag that pulled on the connector and broke it. Then we went to serial mouse, and broke that as well. That's when I learned about the Stylistic...
Thanks to daver56 for the link for the PenServices - this saved me from having to dig through all the directories and find all the files.
