Intel 8085

The Intel 8085 was effectively a later version of the popular Intel 8080 microprocessor. It improved on the 8080 by only needing +5V (hence the '5' in the number), like the 8080's competitor the Zilog Z80; and also by needing less support circuitry.

Its instruction set is a superset of the 8080's, with a few added instructions to handle the added features of the 8085 (a more complex interrupt system, and a built in asynchronous serial line interface); it is otherwise object code-compatible.
