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.
Many microcomputer makes and models could run some version or derivation of the CP/M disk operating system.Eight-bit computers running CP/M 80 were built around an Intel 8080/8085, Zilog Z80, or compatible CPU.
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.
Zilog was started in California in 1974 by Federico Faggin and Ralph Ungermann with support and encouragement from Exxon's computing division. [2] [3] Both left Intel after working on the 4004 and 8080 microprocessors and custom chips. Masatoshi Shima, who also worked with Faggin on the 4004 and 8080, joined Zilog in 1975. [4]
The NEC μCOM series is a series of microprocessors and microcontrollers manufactured by NEC in the 1970s and 1980s. The initial entries in the series were custom-designed 4 and 16-bit designs, but later models in the series were mostly based on the Intel 8080 and Zilog Z80 8-bit designs, and later, the Intel 8086 16-bit design.
The Z-2 was a Z80–based microcomputer system that was introduced in 1977. 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.
SYmbiosis Multitasking Based Operating System (SymbOS) is a multitasking operating system for Zilog Z80-based 8-bit computer systems.. Unlike early 8-bit operating systems, SymbOS is based on a microkernel, which provides preemptive and priority-oriented multitasking and manages random-access memory (RAM) with a size of up to 1024 KB.
This led to a new concept initially known as the "Super 80", but eventually emerging as the Zilog Z80. The Z80 was a significant advance on the 8080, running on a single +5V power supply and adding several nice features from the Motorola 6800. Released in 1976, it was soon a huge hit. [3]
