PPC512/640 DIP switches

The PPC series computers have 6 DIP switches, but only 5 are used. With the PPC open and flat, the switches are down for on, up for off.

SW1: Internal/External display

This switch should be turned off to use an external monitor, on for the built-in LCD.

SW2: Video hardware emulation

If this switch is on the built-in video adaptor emulates a CGA. If it is off, MDA.

SW3: Disable internal video adaptor

Turn this switch off to disable the built-in video adaptor and use an add-on display card. This would require a third-party docking bay, since a standard PPC has nowhere to plug the card in.

SW4,5: Initial Video Mode
