<p class=MsoNormal><span style='color:#1F497D'>Sort of related (in a car parts
sort of way…not in a Quad way), Bosch telecine’s used the same
lights as Volkswagons for the front panels…and you could probably buy the
parts from an auto parts dealer for a 10<sup>th</sup> the price of the
manufacturer.<o:p></o:p></span></p>

<p class=MsoNormal>Bosch were famous for this if they once put a unit together
all their products used the same part, one of the field engineers tells the
story of a Capstan motor going down in a remote part of Africa on a BCN51 and
he bought a Bosch lawnmower in a garden shop which used the same motor, so he
fitted it and it worked. I did wonder how he knew which model Lawnmower to buy,
but I guess as he worked for Bosch……<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The circuits were the same, if they designed a synch separator,
then every time you came to a sync separator it was the same design same print
layout, does not matter if it was a VT, Telecine, or Camera,<o:p></o:p></p>
<p class=MsoNormal>They never re-invented the wheel<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>They also made a cart machine BCN 100 three one inch decks
so fairly boring<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The TC100 was a multi stage mechanical thread with bike chains
and a pinch roller less, wrap around capstan, each stage signaled its
completion to a DTL logic system by micro switches.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The DTL logic was arranged on 200 PCB’s 5 chips per
PCB and about 5 gates per chip DTL uses wired OR gates so you can
interconnect several gate outputs and if anyone goes low it will pull the
others low<o:p></o:p></p>
<p class=MsoNormal>Ie OR function. This is hard to troubleshoot if you have an erroneous
low as you cannot identify which gate is faulty. The Or gates spanned
several PCB’s just to add to the challenge <o:p></o:p></p>
