[QuadList] HS-100 disc

[David Crosthwait]

Hello Bill,

That would be a good group question. Who had experience with the HS 100/HS 200 systems on this list? The knowledge base on these units is dwindling. The last usage I can personally recall was in the 80's for The Breeder's Cup (NBC) when the producers wanted a precision stop action as the winning horse crossed the line. 

The rental market had to be terrific for whose who owned them (if they were taken care of). Even Loyola University's TV department had one available for rent back in the day!
