I personally will travel to Europe around Xmass and intend to use it on
PAL/SECAM TV sets. The statements is, that since the video output is
progamable, one could in principle write a driver to PAL. The unclear
things are whether another xtall will be needed, and whether the voltage
range of the output should be changed. Any book on video signals must
have that info. Although I don't know of any, I'm willing to read one
and write the driver, if anybody can suggest the title.
