Obsolete Motorola ic identification

Hello, looking for information about ic pictured, it is from a 79 pontiac timed relay board.
System doesn’t work at all and without knoledge to troubleshoot the board I planed to replace everything, passive components are easy to find but can’t find anything about ic from reference.
Thought about a kind of 555 timer, board seems pretty simple so I hope someone knoledgeable could help.
Thank you.
