If you are able to pull the firmware, I would like to get a copy. I have a blade here with a fried PIC that I'd like to replace and get it running, and any firmware that works would be nice. I haven't been able to read code on any that I've checked so far.
Pretty gosh darn cool to have a clock-switchable Blade too. That's weird.
Oh hey I recognize that handle, you overclock blades and stuff. I guess I shouldn't be surprised you found this.
I powered my cluster down then proceeded to freaked myself out when the blade simply reset on each read try and failed, I didn't realize there was a "18F_J_" option at first.
Unfortunately this looks like a no-go as all of my blades including the 'unique' one are indeed code protected. Bummer..
If you ever get your hands on the firmware I too would like a copy! I quite want to try and modify the code but don't plan on doing so unless I can recover the blade in case implementing a network stack proves to be too much...but...
Any chance you'd be willing to sell the pic-less blade towards development? Microcontroller code is a hobby of mine and I have a sneaking suspicion there are gains to be had here just like the Block Erupter USB's can be made to run 666MHs with a config flag option.
https://bitcointalk.org/index.php?topic=357684 now imagine a BE blade possibly running 21.8GH on it's stock 12MHz crystal.
EDIT: Hmmm, I might have jumped the gun in the 'speed boost', and not read through far enough it appears it's just faking CGMINER out and the pool hash rate is only slightly rising, but so is error rate. Well, that idea is likely a bust, but I'd still be interested in trying to write my own firmware.
