Monome gs128 on g5 ppc

i just got an old powermac g5 ppc running OS 10.5.8 (leo) –
where can i find and how can i install serialosc on it, and which apps can i run on it?
anyone with a similar setup?
should i look for monomeserial installer/apps also?
i installed already max 5 runtime and supercollider 3.4.5 :slight_smile:

thx in advance
