I'm reminded of the F18A, a replacement for the TMS9918A in the TI-99/4A computer that offers lots of enhanced graphical modes including 80-column mode, and enough sprites, colors within a sprite, and graphical layers to enable games for this 16-bit system to look 16-bit! The F18A also works with other systems that used the TMS9918A, like the ColecoVision.
