The logic circuitry needed to generate and decode signals of this kind has become available only in the past 10 years or so.

A disadvantage is that it is difficult to design random logic circuitry for processors with large and complex instruction sets.

The logic circuitry of the 305 was built of one and two tube pluggable units and relays.

All of the logic circuitry was TTL, and no microprocessors were used.

The computer was based on the transistor-diode logic circuitry and the paper tape equipments.

To overcome this problem the cinema decoder uses so-called "logic" circuitry to improve the separation.

These used two paper tapes, along with logic circuitry, to find the settings of the chi pin wheels of the Lorenz machine.

The other board was the logic board, which contained all of the computer's digital logic circuitry, such as the processor and memory.

This saved on the cost of logic circuitry, enabling IBM to make it inexpensive.

It is remotely controlled and probably has some logic circuitry for hopping about and staying with the other birds.
