Hi i was wondering if theses parts are still avable or not i have an opto board that the ic has the top broke off and i wanted to replace it if i can to see if the board works or not. its for a tron opto board i need to know if the chip and the optic sensor have a cross reference # and if they are still is alaible. the pic is of another bally opto board with A082-91418-DOOO on the board and the chip has 74LS491CJ / 8214 and the chip maker looks to have MMI on it any help would be great.
