Analysis

The power supply of the PS1 is an all-in-one provider for the following:

  • Power outlet hookup through a non-standard C7 power cord.
  • Rectifies, stabilizes and transforms the AC domestic voltage levels to roughly 8v and 3.3v.
  • Handles power on and off by a dual pole switch on the 8v and 3.3v lines.
  • Handles reset through a momentary switch.
  • Delays and monitors the reset logic through a supervisor chip.
  • Provides power and reset logic to the motherboard through a 5-pin cable.
