Simon,
unfortunately I'm not a developer (EPOC, Linux or any other) so I
wouldn't be comfortable trying this.
I guess I'll have to wait for someone else to blaze the way and then
be an early adopter.
Thanks anyway,
Jim

I would have thought that it would be possible to build Microwindows as an
EPOC application, if that is what you are trying to do.... you would have to
make a screen, keyboard and mouse driver that suited EPOC.
[Please note that the last time I suggested that someone wrote another set
of device drivers it caused a small flame-fest, please let's not got there
again.]
This would given the ability to make a single application with Microwindows
embedded in it (like the Microwindows Mine demo) which would run under the
EPOC OS. Note this is an EPOC application that uses the code from
Microwindows.... it has nothing to do with Linux.
It is highly unlikely that you would be able to run an X type 'server' along
side the EPOC OS, but as noted there is a Linux port for this class of
device. Actually this may be possible, but let's not run until we can walk.
I don't have any experience with the Psion 5.But working on the assumption
that you have a build system/enviroment, you should be able to find the
system calls for connecting to the 'screen', clearing and setting pixels on
the display.
I would suggest using the null keyboard and mouse drivers to start with and
concentrating on the display driver. Microwindows is easier that Nano-X and
the 'Mine' demo makes a good proft of principle.
May the source be with you... drop me a note if you need some more pointers.
