This is my MARCHintosh 2025 project post. My goal was to get the physical hardware of a "classic" Mac online and connected with the other folks participating in GlobalTalk. I'm very happy that after years of trying, I actually have a working solution this year.

I recently took my second certification test of this year. I am challenging myself to accomplish as many certifications as possible in 2010. This test was the Support Essentials test for OS X 10.6 (Snow Leopard). It was
