Tim,
Thanks for any help. Well basically I have put together a team of people who will be helping out. I am going to have a few questions for you. For now; I plan to use mach3, but I really want this to be as compatible as possible, so linuxcnc is as important as anything. We have managed to narrow the proc down to one of about 8, the most likely candidate is NXP 80C51 series, it can run up to 33MHz. 32MHz is the closest standard value I believe.
Ideally we would have a chip that can be dropped in place. I need to be clear, the plan is to sell these at the cost of the chip + 20$ and it will be used as a fundraiser for Protospace.ca.
Now all that being said, I still think that we will have to start work with a breakout board. I REALLY want to hear from anyone that has done ANY reverse engineering on the MS10105 USB board, The whole point of what Tim has started here is to make this information public;
**WARNING, TANGENT!!!***
I have been to Omaha hackerspace, Chicago hackerspace, Toronto hackerspace, Edmonton hackerspace, Portland hackerspace and I hear the same thing, over and over, "Had to replace the controller...", Cause lets face it Moshidraw, is kinda ass... Some people like it, I have moshidraw 2014, and while I will admit, it doesnt always crash, it still is poorly designed, especially as it doesn't conform to ANY machining standards for naming. I respect its better than them shipping it with nothing, but I want to make an affordable alternative. Having to drop 400$ on a DSP when you have a perfectly viable solution in front of you is, in my opinion un-acceptable.
**End of Tangent**
I have a K40, ordered several weeks ago, it came in the mail (Canada post football team had there A game on, I had to beat the dents out and then use the CNC mill to fix the gantry.). shipped with moshidraw 2014 MS10105 USB. the board is identical to the one in your photos.
