Holy cow! That's actually the original, FIRST oscillator board still installed in this unit - they apparently never swapped it out for a later one. That makes this a pretty special machine for the right party, because that first oscillator board intact in a machine, while likely pretty problematic to a player the real world, would be pretty important/valuable to the right collector.
