| | Zilog Z80 - Wikipedia, the free encyclopedia |
 | | In the mid-1980s the Z80 was used in Tatung's Einstein and the Amstrad CPC and PCW home/office computer ranges as well as forming the CPU basis for the MSX computer standard. | | | The Z80 was also used in the Norwegian Tiki 100 computers, which were the computers of choice for Norwegian schools during the late 1980s. | | | It was designed to be binary compatible with the Intel 8080 so that most 8080 code could run unmodified on it, notably the CP/M operating system. |

| | Z80 |
| | Z80 is an emulator for the Intel 8080 and 8085 processors, and the Zilog Z80 processor. | | | I wrote this about 13 years ago (even then, the Z80 was archaic) as a test bed for the Computer Emulator Framework. | | | Source is included for the emulator itself, but the subroutine library used by the emulator is available separately (however, the subroutine library has evolved and probably won't compile with Z80 in its current form). |

| | Z80 |
| | The Z80 was a much improved Intel 8080 (as was the Intel 8085). | | | A Sharp Z80 work-alike was used in the GameBoy Color, running at 4 MHz for GameBoy software or at 8 MHz for Game Boy Color software. | | | The thing that really made the Z80 popular was the memory interface - the CPU generated it's own RAM refresh signals, which meant easier design and lower system cost. |

The Z80 is a pure 8-bit microprocessor, which means that its internal registers and data paths (as well as its external data bus) are 8 bits wide. | | | Introduction - ------------ A. We will devote a brief time to an overview of the Zilog Z80 CPU as an example of a "real" computer - in contrast to the abstract models of computation studied in CS220. |

| | Icarus Productions - Z80 FAQ |
| | As the Z80 is an 8-bit processor, these registers are all 8-bit wide, this means they can hold any value from 0-255 (= 8 bit or one byte). | | | The Z80 is able to perform various instructions. | | | The Z80 is indeed a very old processor, I think it was first released in 1977 (correct me if I'm wrong). |

| | Introduction to Z80 Assembler |
| | The Z80 is one of the most popular microprocessors of the 80's having been used in many home computers systems of that era. | | | The Z80 cannot know whether or not a number is positive or signed in this system and handle the two zeros correctly for subsequent instructions. | | | You'll see more about PC later but for now all you need to understand is that memory stores all the information the Z80 can use and it's where we place instructions and data so we can make a computer useful! |

| | Sequence Enumeration |
| | The original Z80 (a 2MHz part) was a souped-up version of the then-popular Intel 8080 processor. | | | The EIR is the same as the I register on the Z80 and thus contains the upper byte of an interrupt vector table. | | | This is much better than the original Z80, which requires a minimum of three or four cycles per byte with many instructions requiring multiple extra cycles. |

| | Z80 |
| | Around 1985, the MSX was a popular homecomputer, based on the Z80 microprocessor clocked at 3,58 MHz. The MSX taught me how to program the Z80 microprocessor. Also, the MSX is capable of running a C-compiler (MSX-C) which turns C languague into Z80 mnemonics. See my MSX page for more information. | | | Also the Z80 has 4 true 16-bit registers: SP (Stack Pointer), PC (Program Counter), IX (X index register) and IY (Y index register) and finally one Interrupt vector register (I). Originally the Z80 runs at 3,58 MHz. A Z80B version is capable of running at 7 MHz. | | | Scanner-1.0.zip contains a C software routine (as well as the generated Z80 mnemonics) which outputs steps to the X and Y stepper motors based on given new coordinates from (0, 0) to (255, 255). The program uses very little calculation (no multiply or divide) in order to speed up the Z80. |

| | A.PRG file is simply Z80 code written to execute in the 16K between 4000 and 7FFF. | | | This is unusual in that as well as having the normal capability to assemble object to a file you can also get it to direct the assembler output to the SCSI card which then blasts it into the SRAM that is faking the Flash on Anne. | | | The equivalent of the system menu lists the main tasks in the machine (WP, Spread, Diary, Addr, etc) but in addition it has an entry to "Run external program" which basically puts up a file selector that lists any.PRG files on an MS-DOS compatible floppy disk or in the machine's memory disk. |
