My Twilight Zone pinball machine is the nearest thing that I’ve got to a family heirloom. Rather sadly, it’s been poorly sick recently, owing to some leaky batteries. These are rather stupidly mounted over the main processor board and covered some important chips with corrosive liquid. Although I managed to get the board back to life by cleaning it up a while back, a few weeks ago the input connected to the game start button failed, which made it rather hard to get a game.
Fortunately, even though (or perhaps because) the machine was made in the mid nineties you can still get replacement circuit boards. These are re-manufactured using the same components as the original and, once I’d got one, my machine sprang back into life.
