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

That may help.

Hello dear fellow time-nuts,

Last weekend I bought a selfmade GPSDO at the fleamarket for a very
adequate price. 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!
