Allied Leisure Pong Board? (URL)

Unsure what game this is from...

Earlier coin-op game circuit board that we believe may be a sound board from an Allied Leisure arcade game.  Board is labeled "Ali-947" and "1155" on the front and Universal Research Laboraties  (1975) on the back.  We believe URL made boards for Allied Leisure games.  We are guessing this is part of a Pong clone game.

Board is untested and sold as-is, see photos for more details.
