I got a free Mac Classic some time ago, and on my quest to clean the garage, I have decided to fix it up to add to the collection. I glanced at the board for bad solder joints, but didn't find anything. Just to be sure, I freshened the solder on the connector to the deflector coil, still no...
Let's take a better look at this:
I read what unity said in the forum above, and it looks like I put the cap polarity in the same as the others. I reverted it, same result. If you take all load off, such as floppy and hard drive, it stays on if you are holding the power button. Once you plug...
The Apple II came with the monitor and I did get output from the monitor. I didn't really test them too much, I just wanted to make sure they fired up.
I wasn't too familiar with the Commodore stuff, and I am used to the floppy drives being powered from the computer. The size and way it works...
It turns out there is no printer with the Commodore, rather the 5.25" floppy drive which weighs a lot and is about the length of a keyboard!
Remember, this is a floppy drive!
I called my electronics surplus shop and was saddened to see that most of the systems I wanted were bought by someone else, however it gets better.
These systems were in boxes wrapped in the garage waiting for me!
Here's how the story goes:
When my parents were looking for something to get...
The Mac would probably not get used too often, maybe a few times a month. I like to keep the Macs in working order before I put them on the collection shelf, in case I do want to use one or get parts from it.
From what you said, I think general purpose or low-ESR would do the job fine. Probably...
I want to do an entire analog board recap for my Mac Classic II. For the PSU part (there is a big group of caps, and you can see a green stain around the board where they are) I would be using low-ESR. For the rest, which should be the CRT circuitry, I would be using high frequency.
The problem...

"you can do this in a bucket with a tooth brush"
I assumed he meant to put the actual board in a bucket.
Around 3:30 he talks about ammonia and a degreaser, with some water in a tub to submerge...
I don't think washing is the issue, I soak all the boards in ammonia, acetone, and water in a pan for 5 minutes before scrubbing with a toothbrush, then repeating 1-2 times before rinsing with the sprayer in the sink. I shoot it with a compressor until there is no water, and I try to shoot under...
