    Replacement Push Clips Rivets Fasteners for Macintosh

    I've managed to find near identical rivets used in the Macintosh to hold the vinyl jacket. Some of the older Macs used two sided sponge tape, I would suggest to scrub off that tape and replace it with these. I've also seen people lose them or break them, so I think some folks may need...

    Mac Plus stuck on "Welcome to Macintosh"

    I have a Mac Plus which gets stuck on "Welcome to Macintosh" when trying to boot up from a BlueSCSI. I've tried a different analog board, switching out the rom, and switching out the ram. It gets stuck the same way. The BlueSCSI works fine on another board. I've tried 4MB and 2MB ram...

    BlueSCSI with a 90 degree angle

    I've created a 3d printed case for a 90 degree angled BlueSCSI. This allows for a clean look. It will fit all compact Macs. It's made from 3 printed pieces so that both sides of the case can have a smooth matte finish. It has a simple design with only an opening for the SD card slot...

    Here is a list of all the capacitors needed for recapping the 630-0108 240v analog board for the Mac 128k, Mac 512k, and Mac Plus. This analog board can run on either 120v or 240v. It will operate on 120v if wire W12 is in place, and in 240v if wire W12 is removed. These are the highest...

    Reattaching an Apple badge onto a compact Mac

    Does anyone have any recommendations for a type or brand of glue I should use to reattach an Apple badge? The original glue seems like a yellow layer of goo, and it's still very sticky after 30 years. I want to avoid using things like super glue or epoxy to allow the badge to be removed again...

    Broken Atari 2600 Voltage Regulator Heat Sink Mount/Leg

    The Atari 2600 voltage regulator has an aluminum heatsink. This heatsink is mounted to the pcb board via a small leg, which can easily break off over the years. I noticed my leg was broken when I went to replace the voltage regulator. Instead of buying a new heatsink, I noticed you can...

    Using the Sun to restore a yellow Macintosh ☀️

    I've been looking at the safest ways to restore the color of the Mac without over bleaching the unit or leaving streak marks. Because the inside of a Mac 128/512/Plus is coated with a conductive covering, I want to avoid submerging the case into hydrogen peroxide as it induces...

    Cracked flyback transformer wire

    As you can see in the photo, the flyback wire on this Mac Plus analog board somehow snapped off. I would like to confirm that it's ok to soldier this back on. Will that hold? Could the high voltage/high temperature generated by the component cause it to break again soon after? The transformer...
