I didn't find anything until I got to November 1976. This is a Tokheim Bulletin for "CENTRAL CONTROL CAN MAXIMIZE YOUR PROFITS." It is a system where the customer pulls up to the pump, calls the cashier by way of the two-way system on top of the pump, she presses the APPROVE button, which opens the pump, customer fill to desired amount, console register records sales in money or gallons, then the customer pays the cashier.
Then it goes on to say the dispensers used with this console are the 1150-AT; 1250-A (these two are retail pumps) and the 785 Commercial dispenser and suction pumps. No picture of the 785. The 1150 nor the 1250 made either book, but they look very similiar to 952 which is in both books.
