Cromemco Dazzler

When Federico Faggin's new company introduced the Z80, Cromemco branched out into their own line of Z80-based S-100 compatible computers almost immediately.

Cromemco OCTART

However, the introduction of Cromemco Cromix even in its initial Z80 processor form brought multi-tasking and multi-user.

David H. Ahl

DEC built the VT180 (codenamed "Robin"), which was a VT100 terminal with an added Z80-based microcomputer running CP/M, but this product was initially available only to DEC employees.

Endianness

Other well-known little-endian processor architectures are the 6502 (including 65802, 65C816), Z80 (including Z180, eZ80 etc.), MCS-48, 8051, DEC Alpha, Altera Nios II, Atmel AVR, VAX, and, largely, PDP-11.

Glue logic

Address decoding circuitry used with older processors like the 6502 or Z80 to divide up the processor's address space into RAM, ROM and I/O.

Grundy NewBrain

These included Z80 Assemblers and debuggers, Pro Pascal and Pro Fortran, TCL Pascal, dBase II, Wordstar 3.3, Peachtree Accounting applications, the Superfile database and CP/M versions of Hisoft Pascal, Modula-2, Z80 Assembler and text editor.

J. K. Greye Software

They struck gold with the revolutionary 3D Monster Maze, the first 3D game for a home computer, which John Greye suggested they produce after seeing a basic 3D Maze that Evans had programmed in Z80 Assembler.

Mostek

The Z80 eventually became the most popular microcomputer family as it was used in millions of embedded devices as well as in many home computers and computers using the de facto standard CP/M operating system, such as the Osborne, Kaypro, and TRS-80 models.

MSX Video access method

Compared to the unified system and video memory used by other 8-bit computers of the time, such as the Apple II, ZX Spectrum, and Commodore 64, separate memory has the advantage of freeing up of the Z80 processor's 64 KiB address space for main RAM, and the VDP doesn't need to steal CPU cycles to access video memory.

Nintendo DS

The Sharp Z80 compatible processor used in the older systems is still included, and indeed necessary for some GBA games that use the older sound hardware.

PLAGSD UAV

MJU-1 is an UAV developed by PLAADC, and its existence of MJU-1 was revealed when the provider of its altitude sensor (which is shared by FK-B125 and FK-Z80), Zhengzhou University of Light Industry were identified along with the sensor itself as one of the scientific achievement of Henan province in 2009.

FK-Z-80 is an UAV developed by PLAADC, and its existence of FK-Z80 was revealed when the provider of its altitude sensor (which is shared by FK-B125 and MJU-1), Zhengzhou University of Light Industry were identified along with the sensor itself as one of the scientific achievement of Henan province in 2009.

Programming the Z80

Programming the Z80 is a seminal programming text, written by Rodnay Zaks and first published in 1979 by Sybex.

Racter

According to Chamberlain's introduction to the book, the program apparently ran on a CP/M machine; it was written in "compiled BASIC on a Z80 micro with 64K of RAM." This version, the program that allegedly wrote the book, was not released to the general public.

Richard T. Russell

Richard Thomas Russell is the creator of the BBC BASIC for Windows programming language and the author of the Z80 and MS-DOS versions of BBC BASIC.

Simon Brattel

When at Crystal Computing he was part of the team that produced the landmark ZX Spectrum game Halls of the Things and the Z80 assembler Zeus.

TI-84 Plus series

Several attempts have been made at creating a C to Zilog Z80 assembly assemblers, such as SDCC.

Visual 1050

Chipset: In addition to the Z80 and 6502, the system also included Intel 8255A PIO, Intel 8251A USART, Intel 8214 Programmable Interrupt Controller, Motorola 6845 CRT controller, Western Digital 1793 floppy disk controller, and OKI MSM5832 real time clock.
