        # Amstrad CPC CTC DART

Simple Z80 CTC and DART board compatible with the Amstrad CPC and MX4 connector

![assembled-board](https://github.com/rabs664/Amstrad-CPC-CTC-DART/blob/main/Images/assembled-board.jpg)

## Objective

Prototyping board to learn about the Z80 CTC and DART, and how to write Z80 assembly using an Amstrad CPC.

## Background

Part of a number of modular cards using Z80 associated peripherals and the Amstrad CPC.

## Backplane

[CPC Amstrad Expansion Backplane by revaldinho](https://github.com/revaldinho/cpc_ram_expansion/wiki/CPC-Expansion-Backplane)

## IO Addressing

The IO Address can be selected using jumpers, supporting the following base address.

* F8XX

* F9XX

* FAXX

* FBXX

The CTC is then adressed at XXEO and the DART at XXF0.

See [CPC Wiki IO Port Summary](https://www.cpcwiki.eu/index.php/I/O_Port_Summary) for a list of known IO ports used on the Amstrad CPC.

## Testing

The CTC DART board has been built and simple testing has been completed on an Amstrad CPC 6128.

Note also an FTDI Serial Adapter was used to connect to a Tera Term session.

## PCBs

PCBs are available from [Seeed Studio](https://www.seeedstudio.com/Amstrad-CPC-CTC-DART-V1-0-g-1398289).

## Components

This [Digi-Key](https://www.digikey.co.uk/en/mylists/list/81SQJULUKE) List contains all components excluding the Z80 CTC, DART and FTDI Serial Adapter.
