The Zilog Z80 is an 8-bit microprocessor designed by Zilog that played an important role in the evolution of early computing. Launched in 1976, it was designed to be software-compatible with the Intel 8080 , offering a compelling alternative due to its better integration and increased performance.
The Z80 Operating System with Relocatable Modules and I/O Management (Z80-RIO) is a general-purpose operating system developed by Zilog in the late 1970s for various computer systems including the Z80 Micro Computer System (MCZ-1) series [1] and the Z80 Development System (ZDS). [2]
The NE-Z8000 computer is based around a Z80A CPU clocked at 3.6 MHz with 1KB of RAM [8] (expandable to 16 KB [3] [1] [8]). The 8KB ROM comes with a built-in Sinclair BASIC interpreter. [8] The machine has four plugs on the back (9V DC, EAR, MIC and TV), and an exposed part of the circuit board where you can connect extra equipment. [4] [1]
Its internal clock signal can be configured to run at 1, 2 or 4 times the external clock's speed (e.g. a 12MHz CPU with a 3 MHz bus). Unlike the Z80 the Z280 uses a multiplexed arrangement for its address and data buses. More successful extensions of the Z80-architecture include the Hitachi HD64180 in 1986 and Zilog eZ80 in 2001, among others.
The Dick Smith Super-80 was a Zilog Z80 based kit computer developed as a joint venture between Electronics Australia magazine and Dick Smith Electronics.. It was presented as a series of construction articles in Electronics Australia magazine's August, September and October 1981 issues.

The Zilog Z800 was a 16-bit microprocessor designed by Zilog and meant to be released in 1985. It was instruction compatible with their existing Z80, and differed primarily in having on-chip cache and a memory management unit (MMU) to provide a 16 MB address range. It also added a huge number of new more orthogonal instructions and addressing ...
The original Z-2 in kit form included a ZPU-K Z80 CPU card, S-100 bus motherboard, all-metal rack-mount chassis and dust case, card socket and card guide; the assembled form included a complete set of sockets and card guides, and a cooling fan. The Z-2 series was capable of supporting up to 21 S-100 boards and could be configured with any of ...
