Here's an initial attempt to wiki-fy existing knowledge on the Mega65 system garnered from the user forums and Paul Gardner-Stephen's blog.

It's intended as a draft effort, to demonstrate how this information would look when presented in this form.

For now, I'll just add pages into a linear list below. Later on, as content grows, I'll try provide more hierarchical/tree structuring.

• Motivations and Goals for the Project

• 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)

• 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
