<p class=MsoNormal>Yes, Park,<br>
<br>
Everything that has been stated before, by everyone is correct, the
&quot;C&quot; format was based on the moving head technology, which changed the
dropout position as a result of the greater interchange stability of the
format. We added the &quot;sync&quot; head as an option, to make our machine
the same as Sony. <br>
I was not part of the &quot;C&quot; format related effort, since I had be given
the AVR-3, the last quad, and the largest retrofit program in Ampex's history.
It was developed to be a great machine, but had a product manager who didn't
understand engineering and was also more interested in the editing system we
were working with a Canadian Company, Central Dynamics Limited.<br>
My first &quot;C&quot; format product was the VPR-20, with was the VPR-10,
which did not get to market, revised to &quot;C&quot; format. It was a very
good, but heavy &quot;porterable&quot;( <i>my word</i>, which meant, give
somebody $5-$10 and let them carry the 50lb unit)<br>

Yes, that is the way I remember. Sony insisted on recording the entire video.
My Ampex machines did not have the sync head and I never missed it.<o:p></o:p></p>
