The TCR's and ACR's only had 2 transports. When one was on air, the other was ejecting, loading, and cueing the next spot. For TCR's that time was 20 seconds. The carousel had to advance which slowed it down. Also the TCR's used mechanical threading.For ACR's the time was 10 seconds. The carousel was fully enclosed and moved at lightning speed. The threading was done by vacuum which was also fast. The operator could only access the ACR's carousel by a door which allowed access to 4 carts at a time. A beep would go off when you HAD to close the door since the machine needed to advance the carousel.
ACR's were more complicated to program than the TCR's and usually had a dedicated operator. Since the TCR's were sequentially programmed, the MC operator could switch and load his own TCR.
I never saw that condition on a TCR or ACR with the power supply going out. Occasionally the machine would miss the end of tape marker and the tape would wind off the end of the spool (still inside the cartridge).
