This is a color 1/2inch industrial VTR. It was the last open reel machine Sony made for the industrial market. (They did make broadcast open reel machines well into the 1990s)
The image quality of these machines is as good, perhaps a tad better than 2hr VHS on a "good" day. Keep in mind the circuitry is AC coupled discrete transistor and lacks the stability of later consumer machines.
The audio is terrible! Something like 80-10K MONO with a mediocre S/N ratio. Hey it was good enough for talking heads!
A full reel of tape (7 inches) held an hour. The linear tape speed is standard 7.5ips.
Here's a really good site for these old industrial VTRs if interested:
