It’s time to finish off my Fireball Classic restoration. When I started my Xmas / New Year holidays, I had the goal of finishing this off before I went back to work. Looks like I’ll get there with a day to spare. With the presentation of the machine completed in my last update, I wanted to address the last few operational issues with the machine. The first thing to look at is the MPU board. As mentioned a few times in earlier updates, the MPU board has suffered from corrosion. A battery left in way too long managed to spread damage all around the outer edges on three sides of the board and it had begun to work its way in at the components. Damage was also done to the J4 pins and even the female connector pins on this plug.
I was able to obtain a second hand original Bally MPU board in excellent condition with no corrosion damage at all. The male pins at J1, J2, J3 and J4 were all replaced, along with new 5101 RAM and a lithium battery to ensure there is no risk of battery damage in the future. This one came from a Baby Pacman machine I’m told. New game ROMs were also burned and installed.
I find it hard to believe I’ve had my Galaga machine now for over 3 and a half years. This machine is where it all began for me. Seems like yesterday I was constructing it and playing it for the first time. Before this project, I would struggle to hang a picture on the wall properly. I’ve since gone on to build and restore several arcade machines and I now find myself wrapped up in Pinball restoration and repairs. Time flies all too fast. Recently I purchased a 4/8 restrictor board to install into this machine and decided to fix up two other issues at the same time.
Over the 3.5 years, the machine has held up really well. Even with two young kids in the house, there is minimal cabinet damage and marking. The coin slot has survived a few scares as the kids loved to insert anything they could find into the slot (and if they were lucky, it would pass straight through and come out the return slot – which made doing it again even more appealing).
The last few updates I’ve done have been rather small.. It’s time for a jumbo picture update. In this post, I’m turning my attention to the door of the headbox (something you don’t often see covered in restore threads, so I’m glad to be covering it). It requires a decent clean and there are a few issues I need to investigate (I’ll get into as I go along). I also want to sort out the translite and glass with the aim of getting the backglass installed too. The main thing I wanted to do though is clean the door and head to remove as much of the dust that had built up over the years. Once I started on this path though, it ended up being a bigger job than I had originally thought.
The starting point – the door.
