This project is our attempt to design and build a simple, easy to understand, yet capable single board computer. It reuses the same memory paging mechanism I've implemented in Zeta SBC V2. It uses Zilog Z80 SIO/O and Z80 CTC peripheral ICs and implements daisy chain mode 2 interrupt configuration.

Frank Cringle's Z80 Instruction Set Exerciser attempts to execute every Z80 opcode, putting them through a cycle of tests and comparing the results to actual results from running the code on a real Z80. The exerciser is supplied with Frank's Yaze (Yet Another Z80 Emulator).

2019年7月23日 · Easy Z80 is a simple to build Z80 based single board computer with RC2014 compatible bus connector. It contains everything needed to start experimenting with CP/M (and FUZIX). This is an open...

The Z80 CTC module (SC102) provides four programmable counter/timers with very flexible input and output connectivity, as well as support for Z80 mode 2 interrupt daisy chaining. All four channels have an external clock/trigger input, and the first three channels have a zero count/time-out output. All of these signals are available on a connector

Zeta SBC V2 is a redesigned version of Zeta SBC. Compared to the first version this version features updated MMU with four banks, each one of those banks can be mapped to any 16 KiB page in 1 MiB on-board memory. It adds Z80 CTC which is used for generating periodic interrupts and as a vectored interrupt controller for UART and PPI.

EASY Z80 Single Board Computer V1.1 with RC2014-Bus Interface. Author: Max Malinov & Sergey Kiselev (also author of ZETA SBC V2) Projectpage: https://github.com/skiselev/easy_z80. Easy Z80 is supported by RomWBW v2.9.1 and later. RomWBW includes BIOS, CP/M-80 2.2, Z-System, and a collection of utilities.

2021年9月2日 · A Z80 CPU implementation for the Arduino Mega. Offers complete documented and undocumented emulation of the Z80 CPU, capable of executing machine code in stepwise or cycle-wise fashion. This library is compatible with all architectures so you should be able to use it on all the Arduino boards. Was this article helpful?
