We consider (tissue) P systems using non-cooperative rules, but considering
computations without halting conditions. As results of a computation we take the
contents of a specified output membrane/cell in each derivation step, no matter whether
this computation will ever halt or not, eventually taking only results completely consisting
of terminal objects only. The computational power of (tissue) P systems using
non-cooperative rules turns out to be equivalent to that of (E)0L systems
