20: Mitsuzen HDI-10 (Left Hand)

Instructions

There are three nerve signals that need to be relayed: muscle control (M), which runs from your central nervous system (CNS) to your hand (HND), and heat (H) and pressure (P), which run the other direction.

For each signal, read a value from the input nerve and relay it to the output nerve. Repeat ad infinitum.

It is not necessary to leave no trace. Your EXAs should be written to operate indefinitely.

For more information see "Debugging the Phage" in the first issue of the zine.
