We read the book:

o "On the Edge: the Spectacular Rise and Fall of Commodore", Brian Bagnall, Variant Press, ISBN-13: 978-0973864908

and were reminded of the 65816 and its compatibility with the 6502, and this sparked off everything else.

We used lots of useful tools

• Several emulators: run6502, lib65816, py65
• cc65's ca65 assembler (supports 65816)
• srecord utilities
• Edgewall's Trac for our project intranet: wiki, issue tracking, source code browser
• Stephen Williams' Icarus Verilog for circuit simulation
• GTKWave waveform viewer
• Subversion for source control
• GNU Emacs for text editing (and loads of other GNU utilities)
• Ubuntu linux distribution (and lots of packages found within)

including some commercial tools

• Xilinx webpack free of charge, cross-platform, GUI or CLI
• Cadsoft's Eagle PCB layout - free for non-commercial use, up to 3" x 4"
• Google for searching, website, gallery
• Apple's Mac OS X, and Parallels virtualisation
• Sun's VirtualBox

We learnt from many related projects

• Ruud
  • André
  • Samuel's Kestrel
  • Daryl's SBC series
  • and many others

We frequent several treasure houses on the web

• 6502.org forums and many pointers to other resources
• Jonathan Harston's mdfsnet for all sorts of BBC micro related info, and the BBC-Micro mailing list archives
• Jon Ripley's BeebWiki
• PageTable

We bought from several suppliers

• Maplin, Farnell, Digikey for components
• MCUMall
• Robot Electronics
• PCBPool
• Western Design Center

And there are several things we're considering or looking forward to using:

• OHO FPGA modules from Trenz
• Gschem and PCB from the GEDA (open source PCB software) project
• Ulrich Hecht's 65816 C compiler snes-sdk
• PCB Train
