service manual , or info on how to replace , bypass clock battery stop

Equipment: fluroscan 50200

Where can I get a new bios or the floppy discs to fix the bios? Or a new motherboard? 

How do I find the battery on the mother board from the front of the machine? There appears to be two levels of the board, one with a blinking red light, and one under that. I don’t see anything that is in the shape of a CMOS battery.
