Looks like a nice machine with a loyal following
(back when I was looking at a Psion Netbook Pro
). I never got a EPOC version myself, but maybe
http://www.ericlindsay.com/epoc/sisync5.htm can help. The Neuron site looks like it'll lead to nConvert in an uncrippled shareware version. My quick scan didn't see a registration unlock code, but it may be there
(per the developer's comments
). Good luck.
