mega6502's Introduction

Mega6502

Mega6502 is an experiment implementing a minimal 8 bit platform using an Arduino and a 6502.

Hardware

Mega6502 requires an Ardunio Mega 2560 development board and CMOS 65c02. The 65c02 should be connected to the Arduino as follows

	  5v      GND                                 5v   Arduino
