Galaga Restoration, My First Attempt.
Mauzy:
Wow. Im surprised you get it playable with 4.5 volts. Ive never had any luck with anything lower than 5, but I guess my board proved to be a little flaky. At any rate, keep in mind that Galaga boards were notorious for having really crummy sockets when manufacted over 20 years ago, so imagine an already iffy socket plus 26 years of use. You could have perfectly working chips and a dead board if the sockets suck.
I would recommend convertering from your current linear PS to a switcher. It may help you down the line as your current linear PS continues to age. Theres an excellent conversion kit at http://therealbobroberts.net/parts.html . Scroll all the way to the bottom. You can't miss it. You could always buy a cheap switcher off of ebay and hack the wires too, but this is an easier, safer alternative.

how do I post pics here? looking at the picture from the website you posted I think I may have a switcher powersupply and they just left the old supply in there. I took some pics, but don't know how to post..
What I have is right above the linear power supply is a blue box that looks very similar to what is on the bobroberts website, assuming it's a swticher how do I bump up the voltage?

SUCCESS!!!! Kind of. :applaud:
So thanks to mauzy's post I was almost positive I had a switcher ps, but in the picture on therealbobroberts clearly showed a knob for adjusting the power, I couldn't find this on mine, so I took it off and looked at it, apparently the knob had fallen off, but with a screwdriver I was able to adjust the power up, I now have exactly 5.2V going to my board. :w00t
So I turned on the game and expected it to be working perfect...being the naive optimist that I am...lol. And it is much improved. now during attract mode and when I die, I get that choppy bouncing ball effect in the star field, during play, it is almost normal, but the stars look kinda like shooting stars, they all have faint streaks coming off them up and to the right.
Back to taking suggestions.
Thanks to everyone that has helped so far

ha! All of mine have been like that and the knob itself always seems to be stripped. I don't know how many times Ive had to take a switcher apart to push the knob back out of its hole.
