Oh, do I know that site... :) Thank you for putting all that stuff together there, it's the best M-1000 resource on the web. Really looking forward to your homebrew firmware - have you tried to enlist Fetz, the author of the 1.1.3 patches
PS. Whenever I visit your site, I dream of upgrading my Matrix-1000 with a 63C09 CPU and trying to switch to its performance-enhanced native mode. One day, maybe...
