14: Mitsuzen HDI-10 (Heart)

Instructions

Read a value from the nerve connected to your central nervous system (CNS) and make your heart beat by writing a sequence of values to your sinoatrial (SA-N) and atrioventricular (AV-N) nodes as indicated in the HDI-10 I/O log when holding the "SHOW GOAL" button. The length of each sequence of values should be equal to the value from the CNS divided by -10. 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.
