Identify this cable?

[marmca400]

Good day Hatteras owners, I have a '75 36C.
On the starboard side above the windows I have a 1/2" black cable leading aft. Don't know where the end is terminated. Any ideas?
Seems like maybe a instrument cable etc, not 12VDC or 120VAC.
Thanks

Old Single Side Band cable?

My Hatteras' have had old TV/Cable wiring that looked like that. Older transducer wire is kind of like that too.

Thanks for the input. No markings and it's pinched or terminated in the roof aft of the bulkhead so not coming out.
Guess it will just stay in there like a time capsule...
