	I can never figure out why folks ask questions like this. Spice
	knows how to model transistors, all you have to do is give it
	the parameters from the Data Book! I don't get why anyone would
	want to ftp, like, one or two lines of Spice source!

	The 2N4209 is a PNP switching transistor, TO-18 package

	Vceo:	15V
	Vcbo:	15V
	hFE:	50-120 @Ic=10mA/Vce=0.3V
	Vce(sat): 0.18V @ Ic=10mA/Ib=1.0mA

	Just plug these values in to your standard SPICE model!
