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 …

2023年10月30日 · The Z80 and 6502 processors use different control signals to interface with memory and interface chips. A reprogrammable logic chip, dubbed Fat-Spacer translates these signals as required.

2016年8月20日 · TRG0, TRG1, TRG2, and TRG3 (the triggers) are brought out to a dual pin header block that allows you to easily connect them to either an on-board oscillator or (if the on-board oscillator is not installed) to the system clock.

2019年12月10日 · The Intertec Superbtain was a dual Z80 CPM machine from 1979, with a common rom and some shared memory. One processor ran the disc controller, and the other the application.

It shares the same purpose, to replace the physical Z80 in a Sharp or similar system and provide it with features such as faster CPU, more memory, virtual devices, rapid application loading from SD card and by using a daughter board, better graphics and sound.

2020年7月18日 · You can make a real minimalist Z80 with a Z80, a ‘138 octal decoder, a 27xx eprom, a 6116 8 bit widex2k RAM and a 8250 for the serial port and an 8255 for GPIO parallel ports access.

This is a dual port serial module based on the Zilog SIO/2 chip. It features 2 UART, Port A and Port B, thus allowing your RC2014 to connect to 2 separate devices, for example, a terminal and a printer.

The ZiLOG Z80 CPU family of components are fourth-generation enhanced microprocessors with exceptional computational power. They offer higher system throughput and more efficient memory utilization than comparable second- and third-generation microprocessors. The speed offerings from 6–20 MHz suit a wide range of applications which

いつもどおりのラッピングワイヤの手配線です。 上がuPD7220、下はサブCPUのZ80H (8MHz)です。

The 16C2550 Dual UART adds two serial ports to your RC2014 Z80 retro computer kit. Use on its own for 2 ports or with other modules for extra ports.
