The July 1998 QST had an article on a GPSDO he designed. That may help.

Now I need some more information about it to operate it. It seems to work fine, but I don't understand the displayed numbers, the menu, the lamps, the DIP switches... Can you help to identify it? I couldn't find it on the internet. Here are some fotos... When powering up, the display shows "Brooks Shera GPSVCXO 2014". Enthough that might give me a clear hint to identify it, I only found the starting docs from 1998 or so, but not the actual board. Thanks a lot!
