Re: NES - Apple Sprite card
Right on, I have the sprite card at home but never tried it. It was
designed by Steve Ciarcia and introduced in the late Byte magazine.
Resolution was inferior to Apple's high res mode (256 horizontal pixels
vs 280) but it definitely had more colors (up to 16). All you could
program were sprites of 8x8 or 16x16 pixel resolution. To build an
image such as game backdrop, you have to 'tile' sprites.
I haven't found any use for it yet. It's a unique collector item :)
Cheers!

Once upon a time, there was a video board sold for the Apple II that had
a video processor that worked something like the PPU, it was the
9918a/28 from TI that was used in the TI 99/4a and the Coleco ADAM
(among other computers.)
It MIGHT be possible to design a video card with the PPU pulled from
NESs, however, there would be no software to support it (there was so
little for 9918 card that it never really sold well, except for an
excellent Logo.)
