I acquired this recently:


Now all I need is a SMPTE time code generator and the info for hooking it up to this.. Does anyone out there have any experience with this? Just asking before I go down the rabbit hole.

It arrived with the top PCB completely loose and it isn't lighting up properly. The one IC I pulled on popped right out. I was amazed. It's usually the other way around. But hopefully this means that reseating the TTL will fix everything.

I suppose the Frames display could be used for the date.

From what I recall when I worked for Grass Valley Group, SMPTE timing info can be sent in an NTSC video signal during the vertical blanking interval, or thru a dedicated audio channel. Do you know which channel this equipment uses ?

Channel? My mind is blanking out at the moment. 8/


There are all sorts of timecode generators on eBay but I've never actually worked with any of that so I have no clue. I have a Nixie timecode reader/generator but It's not for SMPTE.
