[R-390] R-390 Date Info

Fri, 9 Jan 2004 17:02:53 -0800 (PST)

A good way is to check the date on the crystals.

The calibration xtal is the easiest to check (but it may have gotten changed). 
The xtals in the xtal deck are not so easy to check, but a reliable way of
dating at least that module.

Also see the bathtub cap neat the PTO for an estimate of frame age.
