Galaga Restoration March 29, 2010
Beyond the monitor, the news was mixed. Galaga was filthy inside like an ancient
crypt from somewhere in Egypt. There were plenty of *live* spiders, a nest, thick
layers of cigarette smoke tar, and assorted other flavors of dirt. I took this
photo after some considerable vacuuming/cleaning work and after fixing some of
the worst examples of how not to wire an aracde game.
Unbelievable. Well, the good news is *sort of* that the original power supply
board was smoked and an aftermarket Happ supply installed. This isn't good if
you're a total purist about restorations, but the new switching style supply is
far more reliable. And--smoke & fires are just bad in general.
But the wiring--ugh.
The power supply and monitor were both wired by twisting the stripped wires together
and wrapping them loosely with electrical tape. Actually, some weren't even insulated
with tape. That's a disaster waiting to happen. I made the repairs before I took
this photo of the results:
In the photo above, you can see the added small black unit that is the Happ replacement power supply.
The red arrows above point to some of the places where I performed repairs to the
"so-called repairs". I spend time doing it right--the rules for a quality job are
1. Work clean. Restrip wires as needed.
2. Slide heat-shrink tubing onto the wire first.
3. Make a good mechanical connection.
4. Solder the joint correctly using only the best electrical solder (Kester
or Radio Shack which is also Kester solder is the best by far IMO).
5. Position the heat shrink tubing over the repair and use a heat gun to finish
Here's a closer look at the wire repairs. It still amazes me that all of the
power leads had been just twisted together by the "techician". Wow.
Another pet peeve of mine is the use of these screw-terminal replacement plugs.
I know they are UL approved and all, but to me a power cord should be able
to withstand a jerk on the wire. Not that it's appropriate at all to disconnect
a game (or anything) that way from the wall outlet, but you know somebody's gonna
yank on it sooner or later. A one-piece power cord is the way to go, IMO.
