Great update, although I must admit, it is just mind boggling that you have a working pinball from scratch. Most "home made" machines LOOK "home made" - This machine looks like it was built around the time of the early system 80s perhaps ? I like the "classic" look of the game. If it was a game in an arcade - I would definitely play it.
At the time i built this i used to have some of my games out in shops/pubs making extra money, and i considered putting this one out on location to see if it would make any money, as it has working and fully adjustable coin mechs.
Never actually got around to it though, got sick of seeing my other games being abused, pulling crap outta the coin mechs ( i was always amazed at some of the things id find jammed in there
)so i brought them home and restored them.
