It is composed of two copies of unix that are hassling a bi-block, as shown below.

Generation 14 reveals that the oscillator is made up of two copies of unix and a bi-block.
gollark: Not really.
gollark: I personally don't really like NuclearCraft as a main machine mod.
gollark: Er, they do, are you missing Thermal Expansion?
gollark: I'd also be burning CPU cycles uselessly to go around satisfying some weird requirement which can be replaced with some clicking.
gollark: Very inconvenient. If I log off I want stuff to actually run.
