# 65816 computer ![example branch parameter](https://github.com/mike42/65816-computer/actions/workflows/build.yml/badge.svg?branch=main)

This is a prototype 65C816-based computer. It features a 1.8432 MHz processor, 1 megabyte of static RAM, a 65C22 I/O port, and an NXP SC16C752 dual UART.

The ROM contains a simple test program.
