	I just bought one from yinuxhk based on your comments last
weekend and it arrived today.

	Has one RS-232 port and two 10 MHz and two PPS.  XLR 24 volt
power connector. Made in Korea, marked HP Z3805A std.

	In very good shape. Seems like almost new old stock.  HP DOCXO.

	Seems rather old based on serial number, serial is 3625Axxxxx
which would be 1996 if IIRC.

	I'm pretty sure what Edgardo bought exactly.
	Are yours this exact version and what age are they (from the
serial number) ?
