<DIV>Maybe someone can answer the question about who made the drop out
units. </DIV>
<DIV> </DIV>
<DIV>Ampex had the unit that was a plug in board for the VR-1200 series.
This was made by them. It did not have the color phase inversion so you
might see the replacement.</DIV>
<DIV> </DIV>
<DIV>3M Mimcom built the three rack unit that was installed in the VR-1200's
that I had. It had the color inversion and even had a test generator for
it.</DIV>
<DIV> </DIV>
<DIV>RCA had a module that plugged into the TR series units. </DIV>
<DIV> </DIV>
<DIV>I heard a rumor that 3M built the units for RCA. Does anyone
know? Was this done only for the later machines? The early ones that
I have information for does not have the color inversion. The early
ones were two modules wide. The later ones that were for the TR-60 and
TR-70 was a single modules. It had a switch on the front that
stated off, mono, and color. There was also a color phase screwdriver pot
on the front. This is the one that I had heard was built by 3M.
