[Wear-Hard] $20 320x240 B&W NTSC monocular HM

[orphrey at gmail.com]

Hi,

There is one cable, which ends in a 3-conductor 1/8" jack just like
you would find on a set of headphones. The wires are video signal,
ground, and power.

According to my notes, the pin-out is as follows:

Tip - 6.2V+
Ring - Video signal
Shaft - Ground

I was wrong about it using the motorola driver chip. The IC in mine is
a Kopin KCD-A300-QB. The PCB it is on appears to be about 1 3/4" by 1
1/4", and has all the wires conveniently labeled on the PCB
silkscreen.
