I have developed a homebrew development board. The main motivation was for the BX-35 (BasicX) but it also supports other AVR 40-pin chips. An overview can be found here http://home.austin.rr.com/perks/basicx/DevelopmentBoard.htm. Please let me know (publically or via private message) if you are interested in more details. If I get a sufficient response then I will post more details. Mike
