The Apple //e project was assigned to me by my engineering teacher after seeing my progess with the Drone project. The computer was given to my teacher by his father in law around 2010 and had not been functional since the early 1990s. His father in law had hoped one of his engineering students would one day fix it and the Computer engineering or Software engineering classes could use it to see how far computers have come. The Apple //e sat in a closet and was forgotten about for almost 10 years until I asked my teacher if I could fix it. He gladly agreed. I started by dismanteling and cleaning all electronics with Isopropyl Alcohol. This is good since  it evaporates quickly and helps get all the dust and dirt off all the electronics and other parts. When we finally get around to testing the computer, nothing happens, we have no voltage or anything, after checking the fuses and finding everything is good I started to look at the capacitors and components in the power supply. The power supply voltage was wrong. The 12v DC line was only outputting 2.3VDC. With a multimeter the problem was a transformer coil which had shorted and destroyed a capacitor, resulting in the voltage being wrong.

After coming to the conclusion the problem was the transformer, I started to do research online to determine what the best course of action was. I could buy a new power supply for ~$100 or spend $50 to replace the capacitors and transformer and hopefully not run into any more issues. I decided to buy a new power supply since it came with a warranty and was new, compared to the 40 year old one which may cause further problems down the road.

After ordering the powersupply and getting it installed everything was very simple and easy, unplugged the old transformer, plugged in the new one, and when I pressed the power button it was like magic, everything worked! 

I tested the floppy disk reader by running the copy of Microsoft Flight Sim 2 and everything works, just as it did when it was new.
