Hi, Jeff,

While this could be timecode, I think it is more likely a Pilot tone of 
some sort given the date.

Here is my attempt at listing the different systems:
http://richardhess.com/notes/formats/magnetic-media/magnetic-tapes/analog-audio/synchronization/

On that page, I link to EBU T3095 which was restored at the EBU site at 
my instigation. You can find the link on my page or go directly here:
https://tech.ebu.ch/docs/tech/tech3095.pdf

If it is a full-track tape with two tiny tracks superimposed in the 
middle, then that would be NeoPilot, one of the more common formats, and 
I can digitize that and possibly resolve it using an Otari EC401 with a 
Studer A80.

We should talk more about this.

Cheers,

Richard
