Restoration – Apple Macintosh 512K

My Apple Mac 512K blew a 470uF cap last year. Clouds of smoke. The replacement cap finally arrived. Will it do the trick and get this great old vintage computer up and running? Enjoy

    Hi Big G

    You might want to have a look at the floppy emulators out there, http://www.bigmessowires.com/macintosh-floppy-emu/
    was wanting to get one for my Mac II se/30 , but thats been postponed probably indefinitely till I can find a ADB compatible mouse and keyboard and find the needed will to repair my mac properly.

    Great video!  My Dad got a Macintosh 512K back in the late 1980s, and I really enjoyed playing games on it.  BUT we got the message "Sorry a system error occurred" with this little bomb icon, more times then I can count!  I still have no idea why that happened, unless we got a defective unit.  I was told that it might have been due to the fact that Steve Jobs didn't want a fan in the 512K, but I can't confirm it.  But when it worked properly, it was fantastic!

    yay Gary! Where did you find a capacitor like that? It doesn't look like a modern piece of kit at all.

    Haha, you're like me, huge step backwards after powering on once you've completed a big repair job. Scared the crap out if me with the explosion too.

    An SD card solution would be the best way to solve this but those things get expensive. Is it not just the 3.5" disk itself? You don't maybe have any other system disks to try? I have a Mac IIsi and a range of Power Macs with floppy drives so I could write you some new ones from images if you like. Usually my motivation for doing this is old games though and there are so few decent old games for these Macs – although Fool's Errand and the other titles in that series are actually pretty decent. Is that drive 400k, 800k or 1.44MB because I seem to remember having a spare 1.44MB one lying around somewhere.

    Well done on getting the system to boot, half the battle with those. The screen looks to be nice and steady as well.  The floppy should not be too hard to find, as they don't use anything too out of the originary i.e. not like the Amiga's.

    When the PDP-1 came out it was actually recommended by DEC to clean the PCBs with soap and water.

    I've never seen an actual hard point on a vintage Mac before, but where you're from I'd imagine those things are pretty much a necessity!

    Great video, but actually the where you replaced the capacitor is the analog board, the board with the ports under the mac is the motherboard. It's from 1984/1985
