About the Mz-2000 PCB

Mz-2000 is an open source AVR/Arduino PCB design by yanataka60, published on GitHub under the MIT license. It is a 2-layer board measuring 115.8 × 142.8 mm, with 25 components from 13 distinct parts.

Its main chip is the Arduino_Pro_Mini_5V, from the AVR/Arduino family. Other key parts include the 74LS04, 74LS30, 74LS10, 74LS273 and 74LS245. By type, the board carries 11 ICs, 11 capacitors, 2 connectors and 1 switch.

From the project

MZ-80B、MZ-2000、MZ-2200でSD-CARDからのアプリケーション起動、BASICなどのアプリケーションからSD-CARDへのロード、セーブを実現するものです。

MZ-80B、MZ-2000、MZ-2200でSD-CARDからのアプリケーション起動、BASICなどのアプリケーションからSD-CARDへのロード、セーブを実現するものです。

MZ-80B、MZ-2000、MZ-2200では「/」キーを押しながら電源を入れる、又は「/」キーを押しながらIPLボタンを押すことでI/Oデバイスとして繋いだROMからプログラムを読み込ませて起動する機能があります。

この機能を使ってSD-CARDからアプリケーションを起動させる機能を持たせたMONITOR SB-1520(MZ-80B)、MONITOR 1Z-1Z001M(MZ-2000)をROM起動させます。

SD対応MONITORからはFD又はFDLコマンドでSDからアプリケーションをLOAD実行ができます。

LOAD実行範囲は、0000h～F7FFhです。アプリケーション、ゲームを起動させるにはほぼ問題ないと思います。

Mz-2000: common questions

What microcontroller does the Mz-2000 use?

The Mz-2000 is built around the Arduino_Pro_Mini_5V, from the AVR/Arduino family.

How big is the Mz-2000 PCB?

The Mz-2000 measures 115.8 × 142.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mz-2000?

25 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mz-2000 design files?

From the yanataka60/MZ-2000_SD repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Mz-2000 design in my own project?

Yes, under the terms of its MIT license, which yanataka60 chose for the repository.

Can I test firmware for the Mz-2000 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
