At the beginning of RC 2017/04 I promised my dearly beloved PET 2001 that it will be transformed into a Color-PET this year. I stand by my promise.
Spring-RetroChallenge lead to a color graphic system on a breadboard. It was capable of displaying 320 by 240 pixels at 256 colors on a VGA monitor. Besides a few quirks it worked quite reliable but was not connected to the PET at all.
During this RetroChallenge I plan to get rid of the remaining bugs, integrate the graphic system into the PET and write a BASIC extension that supports graphic primitives like DrawPixel, DrawLine, ClearScreen, etc.
