I had plans for connecting an old palm but I couldn't find the power supply and it was drained out. (It's a pitty how fast the batteries discharges on the palm, I mean, I used my PalmVx last time just a few years ago.
But when scavaging the closets I found an old HP 320LX (Anyone remember those: http://www.pdagold.com/hardware/detail.asp?d=7 ?) and connetced it following your advice above. Worked from start!
Sooo coool. Soooo Slooow. Soooo practical.
Thanks alot. (Goes to all you who ahve answered this question(
