Biocomputer or not?
Ten examples. One definition. A few deliberately awkward boundaries.
A useful definition has to survive awkward examples. Decide whether each system counts as a biocomputer in the broad sense used on this site.
A biocomputer uses biological material to perform a meaningful information-processing role. A device can be neural-inspired without containing living tissue, and biological tissue can be present without being used as a computer.

The boundary matters
Biocomputing is broader than living-neuron computing. DNA logic and engineered-cell circuits can qualify too. Neuromorphic chips and ordinary artificial neural networks use electronic substrates, while a brain–computer interface describes the connection between a nervous system and a machine.
