My Hurco stopped working and said there was a memory failure , so I know that the Dallas chips ( which are original)
had failed , so I followed Bloke's advice and replaced the memory chips and installed batteries.
But when reinstalled with the board, I now had nothing. neither screen lights up ( even though it did when the Dallas chips failed)
and the control board( with trackball ) failed to light. It's as if I had a power failure ?
So I then removed both the new memory chips and batteries from the board .
Then I started looking for new Dallas chips and was successful with product from Digikey and they were ordered ,
Those were than installed ( Built in batteries) and then placed the board back in the Hurco, and again, nothing, zip, nada ..
I used the ground straps when doing this work
Any thoughts or help
Anyone have the memory board schematic.
Bloke, are you still here ?

I should add, that I was able to temporarily borrow another memory board and when installed after doing the above, all works !!! so i am sure it is a memory board issue
