Editing Psion netBook Pro (section)

== Two hardware revisions ==

There are two revisions, and '''you can tell them apart without opening anything'''. The moulding on the rubber cap over the proprietary Honda-connector port reads:<ref name="roth">Jürgen Rothberger, [http://www.rothberger.net/pages/reviews/psion_netbook_pro.shtml "Psion netBook Pro"] (in German), July 2007, with the original March 2004 version at [http://www.rothberger.net/pages/reviews/psion_netbook_pro_v1.shtml psion_netbook_pro_v1.shtml]. Source for the two hardware revisions and how to identify them, the built-in modem in the later revision, the rubberised covering fitting problem, the port caps, the card slot height, the flash memory behaviour, the Total Recall utility and the ROM update history.</ref>

* '''"RS232"''' — the earlier revision. Serial only over that connector; ships with a serial sync cable; no built-in modem.
* '''"RS232 - USB"''' — the later revision. Adds USB over the same connector, adds a built-in landline modem, and ships with a USB sync cable.
