  1. From the album: Macintosh Classic Analog Board Replacement Components

    CP23 - blue ceramic capacitor - original: HR R 271J 2KV - replaced with: B 271K 3KV (270pF 3000V)
  2. Since this is the only board I have — and because it has a lot of captive wiring coming out directly from the board, I came up with this dirty cheap method of securing the wiring raising the board so to work on its back. There are some holes scattered along the board through which you could pass a 4mm wide screw. If you get this screw to be long enough, you can raise the board so that the wiring isn’t damaged while soldering. You must take care not to damage any vias in the process and you should be aware these protruding screws could function as a lever and easily break the board. But having that into account I have reach to the conclusion it’s the best way of working on the Analog Board (and cheapest). I previously tried using a B&D Workmate and a desktop vise to hold the board but since you can’t get a feeling of the force being applied to this fragile board, I dismissed them both.
  3. I recently bought and repaired a Mac SE - but whenever it boots, about a third of the screen is blurry. I assumed it was a logic board problem, but testing both the SE board in an SE/30 (which worked fine) and the SE/30 board in the SE (which produced the lines) revealed that it's actually an analog board issue. I've already replaced any leaky caps to no avail. Any ideas?
