Greetings!
I hope you're out there making some chips!...thanks for taking some time to help me out.
I have a recently acquired Lagunmatic 310 mill.
Previous owner had a dead screen/keyboard, sent a board in to be repaired (spent $1000).

Once he reinstalled the board-no change! So the mill sat for 8 years, and is now in my ownership. I have been troubleshooting and have a few answers, more questions. For one, no response on screen or keyboard. I attached an external monitor, and there is some life! The dynapath boots, but no inputs on control box have any effect. I figured the problem had been mis-diagnosed, and sure enough there was some damage on the circuit board behind the control panel!

I labeled what I understood, as those contacts show continuity between GND and +5v.
What are some thoughts seeing this damage? I understand the plug in chip to be programmed, so no good to try and simply replace that I assume. Is that IC it is also attached to (labeled Y) also suspect? I'm considering an entire control box on Ebay, but that always scares me (regarding compatibility, function, etc). I'm more inclined to invest time and money converting this mill AWAY from dynapath than diving deeper into an ancient technology.
Thanks kindly for your help and advice, I always appreciate the time people will spend to help total strangers! I would gladly repay with some parts made on my lathe or grinder if I can get this mill up and running-Hey a little incentive doesn't hurt. Of course, who on the forum doesn't have those machines themselves
