Re: [time-nuts] looking for data on time code display

Maybe something like a Datum or AstroData. The reverse code switch is for reading tapes backwards. It looks like a modified standard product. It does not appear to interface w/ a tape search controller. At a guess it's mid 1960s to mid 1970s, to go w/ something like an Ampex FR1800 or similar tap

Try their reading room first. http://www.nsa.gov/public_info/foia/reading_room/index.shtml If there is no information in the reading room, do a FOIA. This information is always run past lawyers, not engineers. Don't be surprised if you get a call from whatever NSA calls their legal departmen

I think I've seen IRIG Time Code SW for the PC that uses a sound card, but I forget where. The various IRIG formats are well dovumented. And yes, Time Code readers were used with high and low speed searches on IRIG tape recorders. You set Start and Stop points and the tape would Play, Stop, Rever

I looked at your first post again and noticed there were apparently lots of TTL circuitry, so it could be an IRIG code receiver, and you should be able talk to it. If you don't have a source readily available, you may be able to fool it into responding a little to gibberish applied from a modul

[time-nuts] looking for data on time code display

I doubt that you will ever find a manual or schematics, but you should be able to decipher enough of the circuitry to figure out how to fire it up and talk to it. The digits should be arranged in either a counter or individually addressable. If it's a counter, you should be able to find a 1 PPS

A while back I picked up a couple of what Fair Radio was calling "data line filters". They have a six-digit Nixie time display (hours, minutes, seconds) and apparently decode and display some kind of analog time code (IRIG, maybe?). It was made sometime in the early 70's; it's wire-wrapped with
