i just picked up an older jokers wild video poker machine, the tag on the side says unidesa cirsa series 300 video. its a decent looking machine, sort of similar to the igt pe+ that i have. anyways it came not working, ive cleaned it up a bit and looked it over. seems like the battery in the unit is dead and theres a bit of corrosion around it. im wondering what type of battery this unit takes. was hoping to maybe change it and see if it works. im getting no signal to the monitor, but the monitor does turn on and the machine lights up. cant really find any info on this machine online, im sure parts will be impossible to find. anyways any help is appreciated. thanks
