I'm here ya know. :-) I'll put them up some time later this week. If I forget
lemme know.
BTW, you will have a very fun time figuring out how this thing works. It's
not very easy, and I'm pretty suprised they wasted this much effort on it,
tell you the truth :-) It's *very* complicated. There are 9 EPROMs, 8 8K
EPROMs with the supercharger code on it, and 1 2K EPROM with the control code
for the on-board 6805. It does indeed send 4 bits at a time to the 2600,
and a 6K data load (for the demo games) takes about 1/3rd of a second, maybe
1/2 at most.
I'm still working on figuring it out, and it's not very nice. They did alot of
tricks on it and I'm still trying to figure them all out... getting an emu to
run the whole demo would be a pretty big acheivement, unless you "cheat" a bit
on it :-)
