Restoring Apple II Color Monitor: A Success
- A palette of Apple II color monitors was found behind a building, exposed to rain, humidity, and heat for 15-20 years.
- Volunteers brought the monitors inside and found that all of them worked to some extent.
- One monitor was selected for restoration due to missing bottom covers on many others.
- The monitor was taken home, and initial testing showed a picture but needed cleaning.
- The monitor was cleaned with Windex and baking soda, revealing the glass in perfect condition.
- Disassembly revealed a dirty interior, with most debris collected in the front bezel.
- Potentiometers were tested and found to be working smoothly.
- The circuit board was cleaned with a brush and vacuum, with no bad capacitors detected.
- Corrosion on the front panel board was cleaned with alcohol and DeoxIT.
- Troubleshooting revealed arcing due to a corroded diode, which disintegrated during removal attempts.

"Diode needed to revive buried computers"
- The diode from Mauser is needed to potentially fix the monitor, with the exact part number to be confirmed in part two; ordering from Mouser is the next step, but if anyone knows the correct part number, they can email it for a quicker solution. Restoring the monitor could pave the way for reviving millions of buried computers, hinting at the possibility of salvaging them from landfills worldwide, although the challenge lies in locating them. Additionally, the Apple version of Pesky Robots is now available for purchase.
