Just for the sake of completeness: I have some French (European) 50 Hz
PAL CoCo1/2s and MC-10s in my collection which do have an RGB out
(actually SCART compliant signals including the switch and RGB select
voltage levels). These should work fine with Roy's box, although a sync
stripping might be necessary to get cleanly separated H and V SYNC
signals (the board outputs R, G, B and a "Composite Sync" signal which
is actualy a B&W Composite Video signal. I don't know whether Roy's box
is able to strip the sync signals on it's own (my C=1084S RGB monitor does).
The space for the RF modulator has been used for the RGB video signal
mixer. There's an addtional 12V generator on the board too. Heres's a 2B
board picture: http://dittel.biz/CoCo/pcb_compl2.jpg and here the MC-10:
German CoCo Nut since 1981.
