The 5000 has IR send and receive, but I don\'t know about the file format. What I am expecting to see happen is the new machine will just take all of the old PIM data and store it in a raw format because it doesn\'t recognize the old format.
I don\'t actually know this though, they are both sharp zaurus products, but with about 6 years between them that makes them fairly distant relatives.
The reason I am asking without having actually experimented with the two machines is that I expect to need a filter, or conversion program of some kind. I also expect that finding one will be a chore, hence the pre-experimentation question.
Thanks for your help.
P.S. To actually answer YOUR question, besides the IR the zr-5000 has DB-9 serial, and the large style PCMCIA expansion slot.
