The Z80, 180, and 380 processor families represent three generations of upward-compatible µPs. The Z80 includes 150 instructions, many of which have numerous variants for operand location and ...

So, I'm curious about the Intel aspect of this. . . The 8-bit Z80 microprocessor was designed in 1974 by Federico Faggin as a binary-compatible, improved version of the Intel 8080 with a higher clock ...

Why it matters: Zilog is retiring the Z80 after 48 years on the market. Originally developed as a project stemming from the Intel 8080, it eventually rose to become one of the most popular and widely ...

The microprocessor feature which probably most enables the computing experience we take for granted today is protected mode. A chip with the required hardware can run individual software processes in ...

Perhaps the saddest thing about the Zilog Z80 is that this humble 8-bit microprocessor wasn’t allowed to live until its 50th birthday. This, fortunately, doesn’t prevent people like [David ...
