I'm away from home right now so I can't check, but the "5K BASIC" was really about 6.5K. I imagine 5K was what their target was and what the advertised and presold it as while it was still under development. Even though it ballooned to 6.5K by the time they were done, they kept calling it 5K BASIC.
Extended cassette BASIC was close to 16KB. Besides adding string support, it also has the "MAT" statement set and a bunch of other features. Nevertheless, it seemed pretty big for its feature set.
So, I'd agree with Al, this is probably 5K BASIC.

You can read the first dozen bytes in the picture, which
are 7 bit ASCII, starting with 1010000 1010010 1001111
"PROCESSOR TECHNOLOGY BASIC"
most likely 4K Proc Tech BASIC, given the tape length..
Jim B. could probably confirm that.
