I did a Google search on the Panasonic MARC system and came across this
tid-bit from a recording book authored by C. Denis Mee, Mark H. Clark.
Here's a snippet from "Magnetic Recording: The First 100
Years"... <br><br>
<i>There were four or five machines in a cart, and each waited its turn.
In 1987 the Panasonic MARC (<b>M</b>-II <b>a</b>utomated

The 7th shop order was TCR100A & SP100A. The Machines where delivered
Standard MONO 70 mil, but upgraded on site by RCA to Stereo Split track
(2 ea, 25Mil plus guard band). The EPIS (electronic program ident system)
was transferred from old to new. I was the NBC BSE Project

<x-tab> </x-tab>I thought
the old TCRs were replaced with Panasonic MII Multiplay machines (I
forgot what they were named) around 1984 or so. If your statement
is true (and I believe you), those new TCRs must have hung on for only
about a year or so.<br><br>

timing. Audio quality is normally a function/limitation of the TAPE
not electronic or copper limitations. The days of quad had near Zero
audio to video delay within plants. The invention of Digital affects
introduced the frame of delay.. and then video frame syncs. Audio delays
followed in ~ about 1987-88 and the Electronic Clap board feature in the
TEK- VM700<br><br>

</x-tab>I add:<br><br>
<x-tab> </x-tab>That may
be true within a TV plant, Phillip, but up until the late '70's, network
feeds carried audio and video separately, which often led to audio/video
synch errors by the time they reached their destination.<br><br>
