The games you labeled "TRS-80" with color graphics are actually from the TRS-80 Color Computer, which is completely different from the original TRS-80, which only had the monochrome blocky graphics (which were actually special characters in text mode).
You missed Ghost Hunter (1981) and Jawbreaker (1981) for the Atari 800, the latter of which actually got Sierra Online sued by Atari. There's also the multi-platform Dung Beetles (1982) by Datasoft.
Also Munchman on the 99/4A and KC Munchkin on the Odyssey2 (Phillips Videopac). Both highly enjoyable Pacman clones that got sued (unsuccessfully) for "look & feel" copyright infringement. KC Munchkin is possibly the best game on the system (maybe second to Turtles or Pick Axe Pete)
They were all still better than the Atari 2600 Pac man release. 40+ years later, I am still pissed about the game we got. I knew none of the 2600 games would look as good as the arcade. But Defender was good, so was Missile Command. When my mom got it for me, I ran home ready to play it. I tore the box open, plugged it in and the game loaded then I felt this wave of disappointment. Not so much a wave, as it was a f'n tsunami. I remained bitter and pessimistic for the rest of my life.
I mean..the concept of having to run over dots while avoiding enemies didn't start with PacMan. Exidy's arcade game Crash (also known as Dodge 'Em on some systems) was basically PacMan in a very simplified maze. And it came out a year before PacMan. And the very first game in this video is CLEARLY a clone of that..not PacMan. At least do SOME research.
Another one you could add is KC Munchkin on the Odyssey 2. Atari sued Magnavox to get off the market. I remember the added a centipede, changed a coupke other things, and called the new game KCs crazy Chase
