I was able to contact Jeri about the Pal to NTSC conversion,
She "turned me on to" a programmable oscillator that can
Be ordered at digi-key at any frequency... although this item
Won't fin in the same spot, it can be glued to the board, and
Then run the pins in...
So I can order this thing at 32.7272 mhz... :) and as she puts it below:
"Hook 5v to it and feed the clock into the pin labeled clk in the schematic.
Clko is used to drive a stand alone xtal, so it wont be needed.
Jeri"
So I think I will order the surface mount resisters for the video correction,
and while I'm at it, I will order one of these
Programmable oscillators... after chatting with digi-key tech we decided on
this model:
Digikey part number: ECS-P85-AX-ND for 5 volt version
http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=ECS-P85-AX-ND
specify frequency when ordering...
ECS-P83-AX-ND is the 3 volt version...

has anyone attempted this method?
If not, (Gulp!) I may go forward and do so...
I will have to be as gentle as possible, as if I mess it up, I can go to plan B
(pal monitor)
Speaking of which here is a very handy kit from parallax which has a 3.5"
pal/ntsc monitor (320X240 native resolution)
And a mini ps2 keyboard... (has a mouse as well, not really needed... )
designed to work with their Propeller microcontroller kit.
