What is the difference between ROM version 1.01 and 1.1?
ROM version 1.01 started shipping in new Series 5s around the beginning of October 1997 and fixes a number of bugs present in the 1.00 ROMs. ROM version 1.1 is expected to ship in the fourth quarter of 1998 and will include major improvements in functionality – though Psion have not divulged what these will be. Existing machines can be upgraded to the new version by Psion for a fee. The ROM is held on a plug-in daughter board in the centre of the machine. Access to the board requires disassembly of the machine and while users will be able to swap the ROMs themselves it will void their warranty.
