Hi, I have problem width CNC2101 controler, after repair 5v and -15V power supply section, all power led's light, on front panel led "?" on and CRT show "00". I found it's supply voltage below 18V. I have schematic but power suply page are missing. Maybe voltage control circuit fault ? On RAM card I have dead battery - data are lost. Are someon have power regulators and supervisor section schematic?
