Dimensions:
0.6 × 5.1 × 1.6 cm (1/4 × 2 × 5/8 in.)
Description:
The microprocessor is mounted in a ceramic dual in-line package (DIP); a grey rectangle with two parallel rows of downward pointing brass connecting pins for mounting the component on a cutout circuit board. Part of one edge of the casing is chipped off and several brass connecting pins with it. Originally, there would have been twenty pins along each long edge totally forty.
The microprocessor itself is centered in a brownish square on the top face of the DIP. It is constituted of a small grey chip connected to several tiny, exposed brass connecting plates around the perimeter with very thin white wires. The brass connectors extend from the chip into the DIP layers and connect to the downward pointing brass pins which in turn connect to an electronic device. The embedded connection is partly visible in this object because of the chip off of the side.

FunctionThe Motorola 6800 is an 8-bit microprocessor launched by Motorola in 1974. Microprocessors are an integrated circuit designed to perform all necessary operations of a central processing unit (CPU). This particular microprocessor had seventy-eight instructions and was used as the CPU of many microcomputers and calculators of the 1970s.
