   The TO-3 package consists of a diamond-shaped base plate with diagonals of 40.13 mm (1.580 in) and 27.17 mm (1.070 in). The plate has two mounting holes on the long diagonal, with the centers spaced 30.15 mm (1.187 in) apart. [5] The cap attached to one side of the plate brings the total height to up to 11.43 mm (0.450 in).

   The 8021 processor scans the key matrix, converts switch closures to an 8-bit code and then transmits that code serially to the keyboard interface on the main system. It will also accept commands to turn indicator LEDs on or off. The 8021 was also used in the keyboards for the TRS-80 Model 12, 12B, 16, 16B and the Tandy 6000/6000HD. [6]

   The package may be through-hole mounted to a printed circuit board (PCB) or inserted in a socket. The dual-inline format was invented by Don Forbes, Rex Rice and Bryant Rogers at Fairchild R&D in 1964, [ 2 ] when the restricted number of leads available on circular transistor-style packages became a limitation in the use of integrated circuits ...

   Through-hole technology uses holes drilled through the printed circuit board (PCB) for mounting the components. The component has leads that are soldered to pads on the PCB to electrically and mechanically connect them to the PCB. Three 14-pin (DIP14) plastic dual in-line packages containing IC chips.

   Conversely, the LM386 audio amplifier may be used to drive a small speaker. Note that higher voltage is required if the LM386 is to be used. Therefore, small signal diodes (such as 1N4148 ) are recommended to create a voltage drop , or use a Zener DC–DC converter with a red LED (in forward, can double as a power indicator) and a resistor ...
