It's amazing what you accomplished! No way did I think that computer would ever work again. And the case looks fantastic. How did you get the rust stains off the plastic?

Sure. I just soldered the little spring clips, there are four of them, directly to the logic board. Normally they are held in place with tension only. It's done the trick and no more screen problems.

Yup, was the clips. I soldered them onto the logic board and all is well.

Seems to be a grounding problem the more I mess with it. Reflowed all the logic board connectors, the yoke board on the back of the screen, and the grounds on the plug. Still intermittent screen power. The clips might be the main problem. Should I solder them on the logic board?

Do you mean the little spring clip tabs that are on the logic board?

I won't be surprised if the solution to this problem is so obvious I should have seen it. My Color Classic is acting up. Screen will stay dark, or come in and be darkish blue, or be on with no color. Thumping on the case can fix this. Or not. I'm guessing a bad sodler joint. But where?

Oh and I use a retrobrite method I learned here. Salon 40 in a dog food container in the hot sun. Worked like a charm. Did all the keyboards as well.

That's a 128k on the far left. Made in early October 84'. It's the one I had a lot of trouble with in another thread.

Thanks! They were my project this year. Took advantage of the summer sun to do all the cases. As for the form factor, I guess the modern iMac is the winner winner chicken dinner on longevity. What's it's been now, 17 years?

Here they are, my modest collection. All work, have had caps replaced, cases retrobrited, and floppies fixed. The Plus I've had since 97'. The SE since 98'. My first Mac was an SE. Bought new in April of 87' for $1800. (Great deal) Hot rodded over the years, 45 mg internal HD, 030...

New ROMS installed and all is well. Boots and runs fine. Floppy Emu has a version of system 1! Fun times. My first Macintosh experience was in 1985 on a similar machine at work. It was an astounding revelation, and this brings all those memories back.

That's interesting info, but I'm afraid it's above my pay grade to implement. I do have a set of ROMS on the way from ebay.

I've scrubbed the pins, they were tarnished a lot. Still no go. In good news I got the 400k drive working! I bought a NOS felt pad for the drive off ebay, installed it, and now it works well. The old pad was almost totally gone.

Switched F6 and F7, installed my Plus ROMS and it booted. Put the original ROMS back in and the same problem. Tried it a couple more times and it seems that I've got bad original ROM or ROMS.

I'll give that a try.

I just have a multimeter, will that work to test the caps?

Hmm, would it boot if I remove F6?

Oh yeah, one capacitor was backwards. I fixed that. Still the same.

Hi everyone. So my recently acquired 128k with the 512k socketed upgrade won't boot now. I had the caps replaced and upon return I get no bong on power up and a screen of vertical lines. Installed a Plus logic board and it boots fine. So far I've reseated all the RAM chips. Cleaned the ROM...
