This is a beautiful condition Mac Plus M0001A. I have spent the last few months restoring this in my spare time.
Here is what I have done:

• Completely disassembled it.
• Washed the chassis, keyboard case, and mouse case.
• Whitened the plastic under UV light. When I received it, it was very yellow. The common method to whiten old plastics is to use hydrogen peroxide and UV light. However, hydrogen peroxide leads to embrittlement of the plastic over time. I used UV light only. It's less effective than the peroxide method, but also preserves the plastic better and resists re-yellowing better. Overall the yellow is much decreased, but not completely gone.
• On the analog board (that drives the CRT), I replaced ALL electrolytic capacitors (over 40 of them), the three RIFA safety capacitors, and repaired cracked solder joints.
• On the logic board, I replaced all electrolytic capacitors (~10 I think), repaired cracked solder joints, and cleaned out the rear ports with electronics contact cleaner.
• Cleaned the CRT glass.
• Opened the floppy drive, completely disassembled it, cleaned of all old lubrication and applied new white lithium grease. I cleaned the read head, and disassembled the drive motor to clean it out (dirty motors won't correctly eject the disk).
• The keyboard was torn down, and EVERY SINGLE KEY was de-soldered, tested for continuity, and repaired if they didn't work. If I couldn't repair the individual switch, it was replaced with a modern mechanical switch. The new switches sound a little different than the old switches. I 3D printed custom adapters to fit new mechanical switches to the old key caps. I also replaced three capacitors on the board, reflowed some old solder joints, and placed a bridge wire between two traces that had a questionable solder trace. The keyboard wire is brand new. To show that every key now works, go to YOU TUBE DOT COM slash watch?v=KCnlVoykVSw
• The mouse was disassembled, the wire/strain relief was cleaned with an ultrasonic toothbrush. I replaced three capacitors, and lubricated the ball rollers.

The main chassis has a minor chip in the corner. Includes power cord, and system software disk. Please recognize that this computer is 40 years old. I have made every attempt to make sure it's working, but there's always the possibility that something in it decides to break after you receive it. It's the risk you take with something this old.
Please, please, please ask me questions before purchasing or anything.
