The jumper controls the clock frequency divider -- /18 for pal and /14 for NTSC iirc (probably not, just got home from the pub :). The vic won't be able to show any graphics -- or at least 15 kHz monitors won't be able to display it. Btw, shouldn't a multisync monitor that can handle 15-20 kHz be able to display b/w graphics in this mode? Anyway, this hack was popular with sceners as it allowed them to pack files faster. -- ___ . . . . . + . . o _|___|_ + . + . + . .
