And it seems to work.. :-) RGBI and syncs from the 80-column
connector, +5V and dot clock from cartridge port, put it all
into A2320 and we have a doublescanned picture. I connected
R->R3+R2 G->G3+G2 B->B3+B2 and I->R1+R0+G1+G0+B1+B0.

The only problem now is that A2320 really needs the dot clock of
the 80-column chip instead of using the dot clock available in the
cartridge port. Because of the different timebase the picture has
some jitter. Maybe I should open the machine and try the 16MHz also..
