Removed from new-to-me PRSalpha 5x10 in the course of update to Acorn controller. I powered up tested all three axes prior to purchase, but couldn't test spindle operation as I did not have three phase power, only single phase. Which is to say, I believe this board to be fully functional but cannot warranty. It appears to be in perfect physical condition.

SB part number 001003 v0.7; processor daughter board v201A
