Old wiki contents

For now, I’ve just copy/pasted links to the old wiki’s content here.

We can move any useful stuff from here into the new wiki whenever needed.

Introduction

• Motivations and Goals for the Project

Walkthroughs

• MEGA65 Prerelease Starter's Manual

  • Steps for how to get your Nexys board up and running with the MEGA65 bitstream

• Preparing a build environment in Cygwin

  • For windows users that don't want to jump ship completely to Linux

• FPGA Development Walkthrough

  • Guides you through the installation of the Xilinx ISE WebPack software and its usage

• MEGA65 GitHub docs

  • Search these github docs via the 2nd search-bar above

  • A few github *.md doc files presently accumulating in the official github repo.

  • They cover some common ground as the existing wiki walkthroughs, with more dev-related details

  • They also have a more linux-centric approach, if that's your preferred path (over windows-cygwin)

Documentation

• C65GS System Notes

  • Existing community-driven documentation of the MEGA65 architecture and internal details

• MEGA65 Memory Map

• Unofficial C65 Manual

  • See Chapter 2 and this post for VIC III specs

  • See iomap.txt and viciv.vhdl for VIC IV specs

  • See Chapter 3.1 for BASIC v10 reference

• MEGA65 Docs

  • (just a few text files accumulating in the github repo for now)

• Remote Serial Monitor

  - handy for debugging

• C65 Kernel Disassembly

  • Courtesy of Paul's Log entry on the matter

• KickStart ROM

• Ethernet Interface

  • Loading data via Ethernet

• Remote VNCing

• Proportional fonts

• CPU Speed Control

• FPU

  • An idea mentioned of having a “Fixed Point Unit”, not sure if it has eventuated yet, but will add this just to put it on the radar

• Nexys Board Switches

Miscellaneous

• Volunteers

  • Post on this forum thread and in the 'contact' form of the main site if you're interested in helping out.

• IRC Channel:

  • EFNet

    #mega

• Shared folder with first demo disk

Handy Links

• • Main home-page of the project, offers the bitstream download for the fpga (password protected)

• https://files.mega65.org

  • The MEGA65 filehost - download the latest games, applications, cores, bitstreams, documentation :)

• • User forum, a good place to ask questions and learn from others. There's already quite a few handy threads to help people get acquainted with details

• • Paul Gardner-Stephen's blog, where he details his adventures and exploits in bringing this project to life

• • Facebook page for the project

• • Google groups page for the MEGA65 project

• • Nexys FPGA dev board used for Mega65 project
