			== Rumored 256 Color Mode ==
			Early system specifications mentioned a 256-color mode, but there is no evidence this ever made it in to production. It may have been present in the early PCB prototypes, and a project is underway to see if this was true.

			* [[Nick Marentes]] researched and documented the efforts to determine if a 256-color mode existed in the production GIME chips.
			* [[Roger Taylor]] began his [[Project 256]] in November 2021. He sent off several GIME chips to be decapped and imaged so they could be studied to see how they worked.
