Anyone of you may have service manual, owner manual and/or schematic for Heath/Zenith (Groupe Bull) 386 system. I need to find out about power supply that fit the motherboard so I can modify the power interface. I search websites and surprise there was nothing for both 286 and 386 system. The motherboard part number was obvious belongs to Heathkit because of "85" means PCB board.

I appreciate to receive help for this situation so then I can build the computer to handle my electronic lab equipment that requires to use Windows XP or MS-DOS with serial and parallel ports.

Thank you,
Steven
