    Apple IIc power switch

    Hey y’all, While I was recapping my IIc the other day, I fear that the green power switch on the back seems to have disappeared, and I was wondering if anyone around here has been in a similar sitch. If anyone knows of a good STL file for a 3D printer, I’d be glad to print a bunch out and send...

    Image washed out after Mac Plus analog board recap

    Ahhhh success!!! As I was doing a bit more reflowing, I discovered that one of the legs of L4 had broken off, though part of it was still soldered in, so it looked like it was still connected. Once I rectified this situation, the screen came up looking nice and crisp, and I think we can now...

    Image washed out after Mac Plus analog board recap

    Y’all continue to be the best and I really appreciate this advice. I just wanted to call that out as I don’t know too many places on the Internet where the vibes are as awesome as they are here thanks to your kindness. I think my next step will be to measure the ESR of the caps in the board as...

    Image washed out after Mac Plus analog board recap

    All good points here, thanks y’all! So, the image was all good before I capped the board, and this afternoon I double-checked and ensured that all the cap polarities were lined up correctly. I also redid all the solder joints on the board to ensure that there were no bridged joints and, well, I...

    Image washed out after Mac Plus analog board recap

    Hey y’all, I really appreciate the advice! So I dug through the Dead Mac Scrolls and wasn’t able to find anything that matched this particular problem. I’ve also dug through a set of schematics for the board to see if I can make heads or tails of what’s cookin. I went ahead and reflowed the...

    Image washed out after Mac Plus analog board recap

    Hey y’all, I’ve just finished recapping a Mac Plus’ analog board and, after putting the machine back together, I was delighted to hear a chime as well as see the screen light up and show a picture. It appears that the computer is functional, but the image on the screen appears somewhat fuzzy...

    Cooling a 601 Processor Upgrade card

    These are two great points; I ended up repasting the chip, taking care to make sure that the level was right this time, and with it all reseated, the machine seems to be stable in 601 mode! It took 3 MacBenches like a champ, and a measurement of the 5V line under heavy system load was similarly...

    Cooling a 601 Processor Upgrade card

    Hey y'all, I recently found an Apple-branded 66Mhz 601 PowerPC upgrade card on eBay that I've installed into my Mystic Color Classic (well, after cleaning off the old thermal paste and applying a fresh coat). After enabling the device and the new memory manager, I put it through a MacBench...

    Requesting help for a Mystic black screen issue

    Oh! One other note, the mod pics are missing the pin 20 isolation that I ended up performing last as I realized that the new board did not have J78.

    Requesting help for a Mystic black screen issue

    I’ve done some more digging over the past few and I ended up picking up another CC which has its analog board and motherboard fully recapped. I performed the 640x480 mod again on this one, cutting far more carefully, applying UV solder mask and making as precise solder joints as I could. Much...

    Requesting help for a Mystic black screen issue

    Hey y'all, I picked up some board cleaning supplies and DeoxIT today alongside a few more tools. I started out by applying some PCB cleaner to the board, particularly around the points where the connector attaches to the board, which definitely removed some gunk. I then took to spacing out the...

    Requesting help for a Mystic black screen issue

    I reinstalled the VRAM and, you bet, I’ve attached two pictures, one with the sense line mod and another with the power modification as well.
