Year 2010 problem no more ...
After more testing by brave volunteers, I'm happy to announce that all NewtonOS 2.1 devices should be ready for year 2010 and beyond. In the patch collection, we now have:
Patch 71J059: Patch for the US MessagePad 2000/2100
Patch 73J186: Patch for the eMate 300
Patch 74J185: Patch for the German MessagePad 2100
And finally, a Patch Remover which removes all user applied patches on NewtonOS 2.1 devices (you should never need this, but I supplied it just in case).
All files are as usual on SourceForge, who have been busy with the download interface, but it's still not quite there yet, the patches are under the "Patches" section on the 40Hz download page.
