[time-nuts] FEI FE-5060A Literature?

[xtronus at protonmail.com]

Hello,

Newbie here.

I have a couple of old FEI FE-5650A rubys (one is Opt 3, and the other is Opt 3 & Opt 12) both of which I
literally dug out of a garbage can. One is marked 'bad' and the other has no markings. I have not attempted
to put power on the units as I would prefer to have a look see on the schematics first and also, to know what
the various options provide. Opt 12 is not listed on any literature that I have, while Opt 3 = 5 MHz Out.

Looked around the 'Net on/off for several years for info, I've found a few tid bits here and there, etc.

Although I have tracked down a marketing flyer and a service manual (TM-0107 Dtd Feb 1998), which depicts
board silk screens, while the document does not actually contain any electrical schematics of the PCB boards.

Does anyone know of or can point me to any available schematics for these old rubys?

With the can removed I noticed a multi-throw DIP switch, anyone know what those settings do?

Also, on sht 12, Fig 4, block diagram, depicts a "serial digital input" into a block titled, "Serial Interface", and I did
track down a FE-5650A RS-232C hack, does anyone know if those signals are brought out to the DB-9 connector,
perhaps via pins 6 & 9 which are marked N.C.?

Thanks in advance,

walt w.
