A good fit is the NEC7220, used in the Rainbow. It was one of the first
graphics controllers to bridge the CRTC and the graphics world as
known now. If you can find one that is a good candidate for S100 for
a 3 or 4plane color system.

There were other graphics cards on S-100 too.
I've seen (recently) an
S-100 card that had one of the TI bitmap & sprite generator ICs on it.
Maybe it would be a fun "extend my S-100 machine" project to add a
simple graphics frame buffer? You could put a frame buffer on the
card, expose a window of the frame buffer via memory mapped I/O on teh
bus and a simple VGA output controller in an FPGA. I don't know what
you'd do with it after that, since it would be so non-standard that
there isn't any "off the shelf" software you could use with it, but it
might be a nice retro-fit! --
