History

Resistors Overheated Example - Front
Resistors Overheated Example - Rear

When Henry from ReActiveMicro first returned to the Apple II he found several systems obtained had Power Supply issues or wouldn't power on. Some systems appeared to work but had very intermittent problems. This cased several issues with testing and projects.

Henry started by diagnosing most issues back to the Power Supply. These units were about 20 years old at the time, and were only designed to last 5 at the most. A lot of the regulation parts were either dried out or had been over heated. Some capacitors even showed signs of being swollen. Any bulging top means that they are damaged, will not function properly, and should be replaced immediately.

After a little research Henry found that upgrade the IIe was quite simple, and created The Apple IIe Enhancement Kit for sale to the Apple II Community.
