/6502-monitor-clkgen

A clone of Ben Eater's 6502-monitor code, with updates for clock generation and RAM/ROM implemented in the Arduino

Primary LanguageC++

Arduino Mega based 6502 monitor

Credits: The base for this code comes from Ben Eater's website. Check out his video's on the 6502. That's what got me interested in the first place. https://eater.net/6502

Features

  • Arduino generated clock
  • RAM and ROM simulated by Arduino

Overview

This version of the monitor allows for toying with the 6502 in a minimal setup. All you need is power to the 6502 and connections to the address and dat bus.

The monitor will provide a clock (on PIN 2), if PIN 4 is held low. You can pause execution if you disconnect PIN 4 from ground.

If you want to get a bit more action going on, you can connect a 6522 VIA to operate some leds. Below is a schematic of my setup at the time of testing.
