I know there is a ton of whirlwinds on here, Just wanted to add mine and see if anyone had some tips for me along the way, I've already started but anyways, here it is.
I played whirlwind as a kid at the local pizza joint, never thought I would end up with one (or afford one) but got lucky and found one in town and did some trading. This is my holy grail pin for sure. The game was not operational when I got it. Replaced the resistors for the displays and that let me figure out what was going on and played a few games on it. I wanted to clean it up good before I did any more damage to it, it was very grimey. I plan on getting it cleaned up as good as I can and getting it playing good. I don't mind the patina on the cabinet (for now at least).
having an ultrasonic to use is awesome, also don't know how I lived without a tumbler before!
I've done some touch ups and a few insert decals, I have a play field protector to put on over it all, Just waiting on my cliffy's to show up before I do that. Had to order a couple other bits too so I'm sort of on hold right now.
