Quickscan G1 interface for Connectix Quickcam-to-C64
----------------------------------------------------

Parts:  1 - 5-pin PC-mount Female DIN plug
        1 - User port connector (12/24 conductor, .156" contact centers)
        1 - 25 pin male D-SUB connector (the kind that can mount on the
            edge of a board is nice)
        1 - 4066 quad analog switch (standard DIP style of course)

The numbers, letters, and indications in parenthesis at each end of the
lines is the pin number to connect to.  The wording outside the
parenthesis (like SP1, /Reset_N, etc) is the name of the pin or connection
at each end of the line.

The Quickcam comes with a little power-connector that must plug into the
DIN connector, as well as the data plug which goes into the D-SUB
connector.

As is normal with Commodore schematics in text form, a slash / in front of
an indication, such as /Reset_N, means that the line in question is
inverted (a low/grounded level means a logic "1").
