[QuadList] History - what is the REAL story

[Dennis Degan]

 > When I worked at NBC in 1978-79, there were only 6 TCR-100s on the 
tape floor, in a lineup along the north side of the building. The two 
TR-70s were not C machines; they were probably TR-70As.

they have the Tektronix 529 as the scope.  The A version had the RCA 
TO-4.  A scope that in my opinion was not that great.

	So I guessed wrong.
	I barely remember the RCA TO-4 scope.  There was one in a TR-4 at 
WYEA-TV in Columbus, GA back in 1974.  My memory of it was like yours: 
it was not that great.
