Description:.
Intel 8080 microprocessor is a successor to the
Intel 8008 CPU. To ease transition to the 8080
Intel made the new microprocessor source code
compatible with the 8008. Interrupt processing
logic didn't change from the 8008, which also
helped to port old software to the 8080
processor. The 8080 processor included many
enhancements:

Maximum memory size was expanded to 64 KB.

Stack size was no longer limited to 7 levels.

The number of I/O ports was increased to 256.

The processor included many new instructions and
direct addressing mode.

AMD was a major second source of the 8080. They
also used the part number 9080.
