Wonderfull !!
Brand new in the manufacturer's box. Carefully stored somewhere for more than a decade. They fire right up and generate 1 pps, 10 MHz and 15 MHz when hooked to a working REF-1. Can be adapted to become a stand alone GPSDO. If you want a "no mods" approach, get the REF-1 / REF-2 combo instead.

Good Little CPU
This little guy is by no means king of the hill in Xenon CPU's speed wise. What it is good for is low power drawn and having good benchmark numbers at low power. It is a great replacement for any of the 55xx series Xenon's. It adds a bit more cache. faster RAM interface, and a few instruction set upgrades.
The big concern with any CPU is - will it work? Those tiny little connections on the bottom are fairly easy to mess up. They are also ESD sensitive. Beware of CPU's shipped loose in a brown paper bag :) These came in a proper ESD box (not an envelope) and worked fine.
