The design used TTL digital logic and shift register memory.

TTL logic ran 10x faster, with 10 timing pulses per core memory cycle.

The early R-Tec automation systems used TTL logic with control parameters stored in dynamic memory.

The video system used part of the main memory and TTL logic to provide video and synch to an internal 5-inch monochrome monitor.

A simple controller can be built using the classic 7400 series of TTL logic integrated circuits.

Unlike later terminals, such as the VT100, the Datapoint 3300 did not use a microprocessor in its implementation, but instead used TTL logic in small-scale integrated circuits.

Successors to the original bipolar TTL logic often are interchangeable in function with the original circuits, but with improved speed or lower power dissipation.

It was superseded by the LSI-2 which implemented the same architecture using standard TTL logic.

This is most commonly seen in TTL logic using 7406 open collector logic.

The whole PGG was implemented with two PROMs and standard TTL logic.
