Z80 CMOS NMOS CPU Tester Bare PCB V1.0

Description

Z80 CMOS NMOS CPU Tester Bare PCB V1.0

Manufactured by DIYIPCB using the open hardware design from djtersteegc/z80-cmos-nmos-tester. Selected version: V1.0.

Design functions

CPU test design using EPROM firmware and selectable oscillator/divider settings to identify Z80 NMOS, CMOS and U880 behavior, with LED data-bus indication and a current-test header.

Typical applications

Retro-computing CPU checks, repair benches and Z80 experiments.

Main chips and components in the design

Z80 test socket; 27C512-compatible EPROM/EEPROM; 74LS193, 74LS573 and 74LS02 logic.

These describe the assembled design. Components are not supplied with the bare PCB, and firmware or host software may be required.

What you receive

One unpopulated PCB. US$2.00 per board. CPU under test, programmed memory, oscillators and all other components are excluded. Assembly requires programming the upstream test firmware.

Images are upstream design references and may show components or accessories that are not included. Soldermask color may differ.
