[comp.sys.apple2] PAL encoder card for apple/apple][

ee7aejf@gdt.bath.ac.uk (Alban E J Fellows) (05/08/91)

I have two PAL encoder cards for the apple or apple][ computers. I would like
to know the way these cards work so that I can use them in a stand-alone 
system. What I require is a PAL video output signal with colour burst. This 
would be acheived by providing the board with effectively zero R,G and B values
and a sync signal. What I need is information on the allocation of each contact
on the edge connector and what type of signal input it needs. I would also like
to know if the RGB inputs are linear or TTL.
