Well on the tape shipped with my EDV-9500, there was
a Japanese version of the old standard Indian testpattern we used
to see.
I could see the lines at the 500 circle, but not at the 550 line
circle, and it diappeared about 1/2 way between the two so I
interporlated it was 525.
Super-Beta I was the rare version - but it was on my SL-1000s, and
it was added to 900's by anyone with electronic skills and a bit of
soldering capabillity.
What killed the 7500s and 9500s was the Yen to dollar ratio was
very very bad at that time and the list price of the machines
virtually doubled from what was originally projected. It left
the EDV-9500 listing at about $3500.
But it was still the finest VCR I've ever owned.
And the editing capability, with 5 second pre-roll was spec'd
at +/- 3 frames, but in 90% of the cases I'd get frame accurate
editing.
I'd aquire something from cable on the EDV-9500, and then bring
it down to SB-II on the SL-1000, and there was virtually [very
little] no loss in dubbing. You had to have a good set and good
eyes when you A/Bed the two.
The resolution on the EDV-9500 when using the metal tape was
superb. The only problems I could see was what was typical
of any analog recording medium, but it really showed up
only in the blues - that were slightly noisier than the source.
