	The following is a *guess*, so use the information with caution.

	I believe that the Model 100 used an "industry standard" 9-pin
subminiature D-connector interface for a bar code wand.  Bar code wands
fall into three categories: (1) analog output; (2) digital output (NOT
decoded); and (3) "smart" with a serial decoded output.

	The analog output variety generally use a 5-pin DIN connector, and
the digital output variety generally use a 9-pin D-connector with the
following pinout and functions (as viewed by the wand):

	Pin 2	Wand output; a TTL line sunk to ground, usually with
		an open-collector transistor.

	Pin 7	Ground

	Pin 9	Supply voltage, usually +5 volts

	All other pins are unused.

	For further information, consult an H-P Optoelectronics Catalog
and look at the HEDS-3000 digital bar code wand.

	Bear in mind that I *believe* that the Model 100 uses the above
digital wand interface, but that I am not 100% certain.
