The Commodore 64 is an 8 bit computer sold by Commodore International, and the single highest-selling home computer of all time. It uses a keyboard-centric form factor, commonly referred to as the "breadbin".
Known Issues
Catastrophic Failure of Original Power Supply
Causes
On some models of the original external power supply (those models most common in North America) the voltage regulator on the 5V DC output fails routinely, producing a large voltage spike that fries the chips on the C64's mainboard.[1]
Solutions
- Only use a modern aftermarket power supply at all costs (the original power brick is virtually impossible to repair on account of Commodore filling the housing with epoxy)
- If using an original power supply then an over-volt protector, such as a Commodore Saver from Ray Carlson, should be used.
- A new power supply can be built with minimal effort using a small prebuilt 5VDC supply and a 9VAC transformer. Dave Farquhar has an easy guide on how to do this.
