The Price is Right - 5/3/95 - Grocery Game cash register malfunction 

And under the new format, $20-$22, he would've won. They didn't start using until about a couple seasons ago.

An error that still would've resulted in a loss.

It was a error due to a malfunction on the NCR cash register. I’ve seen better cash registers than this one has not changed since 1972, but still remains unchanged. New cash registers from the 80’s and 90’s uses florescent displays instead of analog cash registers. But this has not been changed.

@@gameshowguy2000 And Michael Taylor better not call this a technical win on that occasion, had it be between $20-$21 at the time and the cash register added $1 by mistake (or a certain amount), then that is worthy of a technical win, but not in this case here.
