Without an image or sound bite how would one find out the name of an old coin-op arcade game made before the early 90's? There does not seem to be a tag for coin op games and you can only use the game Identify tag if you have media of the game in action.
Without an artifact from the game itself, asking a game identification question was decided to be off-topic for Arqade. In other words, one wouldn't find out the name of an old coin-op arcade game made before the early 90s here, on Arqade.
Not every possible gaming-related question can be asked here, as the Q&A format of every site in the Stack Exchange network doesn't work well with every possible question. Some questions simply are not a good fit for the system and should not be asked here.
Our sister site Retrocomputing Stack Exchange welcomes both game identification questions (as long as they're written for 'old' computers) as well as questions about arcade games and hardware. As always with identification questions, please add as much detail as you can remember and think is relevant.
