I recently picked up a Sigma machine. I barely can get around with Bally S5500's. I know nothing about this machine other than the AC works because the neons work. My first question is: do the MPUs have some form of CMOS battery on them, if so where is it located and what type of battery is it?
I visually inspected both the AC and DC power supplies looking for obvious signs, didn't see anything obvious. I'm attaching a pic of the processor board. Any help much appreciated.

It is a Supercap. If it doesn't charge up within 5 minutes of turning power on you may need a new one.
