I hope I have this model right...someone told me that the Hewlet Packard 320, a clamshell hpc which originally came with win ce 1.0 was upgradable to 2.11 or 3.0. Is this true? I can't find anything online to say either yeigh or nay to this.
The model you are referring to, the "320LX Palmtop PC," runs Windows CE 1.0, but can be upgraded to Windows CE 2.0 by means of a ROM upgrade...
Good luck trying to find the ROM upgrade though- the 320LX Palmtop PC is nearly 10 years old and ANY accessory for it is hard to find (especially something as obscure as that)!
I guess you might find something on ebaY if you're patient...
