Then there was the Zenith Z-100 (or H-100 for the Heathkit version) — 640 x 225, 8
colors, IIRC.

I wrote a graphics library for it in C for my own use.  An interesting challenge —
the way the 
graphics were implemented was WEIRD!  The three R, B, B planes were separate 64K 8080
segments, 
and it used this memory in a non-contiguous manner.  Lots of fun to work out with the
very 
limited documentation provided.  But I did end up with a usable C library.   :-)
