Hello all,
I've been playing again. I have almost finished the console driver (with
virtual consoles) and have a basic keyboard driver in place. I've tracked
down the timer interrupt to 0x79 (don't ask...) and this appears to function
OK.
The 'Code So Far' is on my web page for anyone wanting to try it for
themselves (http://www.mungewell.ndirect.co.uk/psion/beyond.htm). Please
note that it still needs a LOT more work, so don't be too judgmental.
I've had a few quirks about fitting a different architecture into the master
tree (as the overwriting of files in this patch proves). What are people's
view on how to do this. Personally I feel that the Psion is significantly
different to justify it's own tree, which could contain variants for the 3,
3a, 3c, 3mx and workabout (If people want to write the code :-).

PS. it works at 0.7 Bogomips!!
