What fun can be had with a symetricom S300

[Marck]

I have the opportunity to get a hold of a Symetricom S300.  Part number 1520R-S300-RB.  It has the Rubidium oscillator.  I was wondering if I was to get a hold of it what fun things could I do with it ? Apart from having a stratum 1 clock in the house. 

I think it only has a few years let until the gps epoch will cause it issues with reported time.

Any ideas or advice for fun things to do with it would be appreciated.

Thanks
M
