My computer just quit, never happened before ( I know you heard this before). I had just downloaded the sketch to a JeeNode, I had not saved it yet before downloading. Is there a way to retrieve the sketch into the Arduino IDE?

Can't be done. By the time a sketch has been sent to a JeeNode (any microcontroller), it has been "compiled" into a set of very low-level machine instructions. The text you see when editing your sketch in the IDE never gets to the microcontroller.

I slightly disagree on this point. It can be done with a decompiler like IdaPro. http://www.hex-rays.com/idapro/gallery/avr.htm which now supports Atmel Avr instruction set, but yes you will not get the original source code but you can patch it if you want. You just need to get used to it, I did for 10 years but on other architectures!

I had a hunch someone might disagree ;)
You're right, of course. If a chip can perform a task, then a human can decode those same instructions (with the help of tools) and deduce the original logic. But having assembly language is not quite the same as having a C/C++ "sketch" - that'll be even more work. I also think that's probably not what @hve was looking for...

Ah yes indeed. But maybe after this conversation he will start to learn reversing. Who knows!

I think I will save my work more often. Seems a lot easier.
