I have a 1996 Sabre 750 with A2100 control. Had to replace the x axis servo cable, and it was done without problems. Changed the batteries while it was down just to be safe since they had not ever been changed. I downloaded intructions from another member on this forum, made the jumper cable and changed batteries without losing power to the boards as was described in the instructions. First error message that comes up is "NC ENGINE BASE FAILED" When I continue to boot up the machine I got the following on the Hardware Diagnostic Startup Status Screen:
Bridge Board (RT) 0 Unknown
Conv Servo 0 Unknown
High Density I/O 0 Unknown
Pendant?panel (MSL) 0 Unknown
Realtime Processor 0 Unknown
Bridge Board (WS) 1 Passed
Workstation Processor 1 Passed

When I use the mouse to click on the Home button I get the following:
-(s_curpos_dsp(0)). Value is set to 0

Nothing happens when I push the power button, no power up, no messages.
I'm lost and in a deep hole so any help or suggestions will be greatly appreciated. I have to get this machine back up and running so whatever it takes. . . .
