<DIV>This is a hard one.</DIV>
<DIV> </DIV>
<DIV>I see in the picture of the Bosch Ferenseh quad that was distributed
earlier, knobs that look like this. RCA did not use anything like this
prior to the TR-600. </DIV>
<DIV> </DIV>
<DIV>I also thought it might be the test button on the optional vector scope
installed in the bridge for monitoring.</DIV>
<DIV> </DIV>
<DIV>Other than that, no clue as to what function it did.</DIV>

<DIV>For this weekend's challenge, identify the function of this control and
what machine it is on. As far as I know, it is the only control of
this design on any quad machine.</DIV>
