I have put together an initial plan for the wiring of the cab. Most of it is very straight forward. The only tricky bit really is the power wiring. But after sketching out a few plans, and getting some expert advice from experienced cab builders, I think it has come together nicely and is fairly straight forward. Another thing I like about this plan is it should help ensure the insides of the cab are tidy, organised and easy to maintain (not to mention safety first also!).

Wiring Plan V1

I’ve added in a filter and varister to deal with spikes that may come through, but probably the biggest decision I made was to use a power board to power the key components of the cab. This makes the wiring simpler, and certainly easier to replace, expand or upgrade features. So things like the monitor, switcher and marquee lighting can all plug directly into the power board. It will increase the cost slightly, but not much. In the end, I think its going to work really well.

A month has flow by now, but I’m pretty happy with how things have progressed. I would have loved to see more happen with the actual cab shell, but that’s should start to move forward over the coming fortnight.

So in the first month, I’ve been purchasing lots of bits and pieces for the cab itself. I now have the JAMMA board, a power supply, a 21″ monitor, JAMMA harness, buttons, joystick, components for a service/test switch, a coin mech, a coin counter (waiting delivery) and some other small bits and pieces for building and mounting.

This month, I’m expecting to get the basic shell for the cab put together and hopefully have the PCB, power supply and monitor all mounted inside.

Another Galaga cab project link to share (link). There is some great reference material around. Although I find some important bits missing in most. So I hope I can cover the missing bits with the blog to help those who come after me with understanding more about what’s involved with getting the internals hooked up and going.

As I draw closer to cutting up some wood to begin the actual cab itself, I have been reconsidering a few of the original decisions I had made regarding the cab shape, size and placement of the internals. One of the original inspirations I had was a cab by Homepin. It’s a lowboy multiboard, and I loved the internal design. Here is a link. (Note: For those of you looking for good write up on building a cab, this link should prove useful! There is a good parts list and price break down, clear photos of the build process and some cool ideas for the internals).

What I loved most about this cab was how everything was built into the door. Open the front door and everything is right there. Great for construction and maintenance. My original goal was to do a similar thing, but with the Centipede cabinet. But lately I have been leaning more towards a Galaga cabinet. The reason being is I grew up playing Galaga. It’s one of the driving forces behind building this cab. I think I would love and appreciate the final result more if the cab closer resembled an actual Galaga cab.

A link I came across a few days back was a Galaga cab restoration. I was very impressed by how clean the internals were and the final result of the cab. I remember saying “I’d love to sit down and play on that!”. And that’s what I want with my cab. So it’s got me rethinking a few things 🙂

So this changes a few things – but mostly, I cannot have a front door with everything right there. It will have to be a rear door, like the actual Galaga cab. I still plan on having a secondary game button, and MIGHT try and find room for a trackball on the control panel so I can play the trackball games on the multiboard (if a choose). The coin door on the front I think will be modified for my cab. It will exist, although in a cut down version. I would like to hook up the test/services switches just inside this door for easy access (instead of having to go via the back). But otherwise it should remain about the same.

The multi board is quite small, so will required much less space than the original Galaga PCB. What I am thinking is attaching everything to a removable board at the base, and allow for a vertical board on the side, should I choose to install an original PCB in the future. The front panel will contain the coin mech, coin counter and test switches.

I still have about 2 weeks before I get the wood and being cutting, so there is still time to clear my thoughts. But the more I think about the final result, the more I lean towards a Galaga Cab…

After looking at a few custom projects, I noticed that people had gone with using an IEC socket.

IEC Switch and fuse

It takes the standard power cables used with most (if not all) PC’s. It also includes a fuse. It was pretty cheap (under $8) and I -think- will be the best option for me. Ideally, I want the one switch (this one) to power on the entire cab (board, monitor, fans, marquee, etc) and this switch seems to be capable of this. Now I’m off to do some more research on just how to wire this up to do just that.

The coin mech turned up on my door step today, so thought I would post a quick photo of it.

Coin Mech

You can probably see the edge of a yellow disk on the left. That is where I can set the acceptable coin size. I’ll replace it with a 20c piece later on. The supplied cable is shown too. The two grey wires are for the coin mech. Overall happy enough – this should do the trick nicely for the front of the cab.
