Do I have these > correct? Fuses are a bit tricky. You can sort of brick your device. It will not talk to you any more, and ways out are with varying tricks ... So be careful. I do not have a 2560. If I had to use one, I would hunt down the data sheet and read the section about the fuses. And this is plenty confusing stuff. Try to translate the above settings into words. Bit by bit. There is also a "fuse calculator" somewhere online ... http://eleccelerator.com/fusecalc/ There is even an Android App for this LOL! https://play.google.com/store/apps/details?id=me.chayan.avrfusecalculator&hl=en_US&gl=US Again: Do not brick your only one device! If you can possibly help it :-) I have done this. So you don't have to, right? > Once I get this figured out, I'd like to submit a write-up for newbies and > perhaps draw more users into AmForth. There is some document about your setup ... vom Karl maybe ... http://amforth.sourceforge.net/UG/amforth_user.html http://amforth.sourceforge.net/UG/windows.html I have no idea how useful this is today.
