Sorry to revive this long-dead thread after almost 13 years, I had MistralXG project on my to-do list for more than 10 years and I finally got to make the PCBs. Alas, meanwhile, Stever's website is down and Wayback Machine (https://web.archive.org/web/20210206041027/http://www.grapevyne.com/pic.projects/) only stores the primary site, not the linked images or other files. That means that I'm left with no firmware - anyone still has the binary HEX for PIC 18F2550 with (updated, based on the archived webpage contents, it should be v1.05)? Or even the sources, maybe?
Thanks,
freddy
