#1 (pic 1856) is a Home Run Hitter PCB, made by Coin Concepts.
#2 (pic 1860) is an LED display PCB from either Rock & Bowl or Wheel Em In, mounts inside the game and shows the error codes.
#3 (pic 1871) I think is a Power supply PCB from the same Rock & Bowl and Wheel Em In (they might use the same PCB's, I'm not sure)
#4 (pic 1879) is some kind of a sound board, maybe Home Run Hitter is my guess.
#5 (pic 1882) I have no idea what it is, if I had to guess I'd say it's a redemption PCB, seeing as the rest of this stuff appears to be the same.
#6 (pic, oops I didn't catch the number) Konami sensor PCB's, possibly some kind of a basketball game, or something that needs to sense a ball/coin. Not too sure on that one, maybe that early 90's TMNT redemption piece...can't remember the name of it offhand.
#7 (pic 1909) Planet Earth sensor PCB's either for a Surfin'Safari, Dinoscore, or Grand Treasure Falls. They're basically all the same.
#8 (pic 1921) AC motors for a redemption game of some kind. Never seen exactly those before, possibly aftermarkets?
#9 (pic 2030) - No ideas, sorry....some kind of optic sensor, but as to what game, I don't know.
Hope this helps you out somewhat anyways.
