I always wanted an extra tier, flip the flipped access to a second bank
of RAM, kinda like a video card. CPU <> SAM+RAM <> CoCPU <> SAM+VRAM <>
VDG. The CoCPU mainly helping add textures and such (think Fractalus
with trees). That CoCPU could babysit a math chip faster than a 6x09 can
divide;-)… Maybe someday I can really retire to create my monster.
