PS/2 type keyboards and mice are supported by this kit as well as standard VGA monitors. The VGA-PS/2 Adapter Board Kit was designed for use with the Propeller microcontroller, and the I/O connections are designed to line up with P16 through P27 on the Propeller chip. When using these I/O pins this board is directly compatible with the Keyboard, Mouse and VGA objects that are also used with the Propeller Demo Board. These objects are available in the Propeller Tool Library as well as on the Propeller Object Exchange.

VGA-PS/2 Adapter Board Kit ( 28075) v1.0 8/20/2009 Page 1 of 3 Assembly Instructions Step 1: Locate the VGA-PS/2 connector assembly (left) VGA-PS/2 Adapter Board PCB (center) and 14-pin SIP header (right). Step 2: Very carefully install the connector assembly into the PCB as shown, taking care to make sure all pins are straight. Make sure that none of the pins were bent underneath the connector, but all are properly inserted into the PCB. Once the connector is seated in the PCB you may solder the connector in place. Step 3: Take the 14-pin SIP Header and solder it in place so that the pins aim downward. In this manner the Adapter Board can be installed easily into a breadboard. If you instead planned on soldering wires, a ribbon cable or some other connector you can do that here instead of using the included 14-pin SIP Header. Copyright Parallax Inc.
