[time-nuts] SRS TSD12

[Shaun Merrigan]

Folks,

I have noted that a number of Stanford Research TSD12 Rubidium standards are available on the auction site.  I searched the TN archives and the interweb and came up with little useful information.  
Does anyone have any information about these units?  Is it a rebadged PRS-10 made for the Telecom market?

The connector pinout is identical to the PRS10, at least. 

TIA,

Shaun M
