I have a "SPRITE 1" by Synetix Systems, Inc., 1983, with a TMS9918A,
eight
memory chips (8328GVP  AM9016FPC), four 74LS chips, one other chip,
video
input and output RCA jacks, and the usual assortment of descrete
components.

I also have a manual called "apple-seed II" which has parts lists,
component layouts, and instructions for assembling Apple II compatible
cards.  Page 3-3 lists a Sprite Graphics Card which also uses a TMS9918A
chip but has a different layout and only one chip (74LS00) besides the
9918
and memory (TMS4116) chips.  

The original BYTE magazine article is: High-Resolution Sprite-Oriented 
Colour Graphics by Steven A. Ciarcia; page 57; August 1982.
It does have some 6502 assembly language listings.
