What's a cheap, easy, and super compact way to step down a 5v signal to 3.3v without a logic level converter? I'm not doing serial or any complicated communication protocol, it's just an on/off switch basically. and I only need one-way functionality
I had another weird Mac dream. This time it was a PowerBook 140 that kept restarting in a loop before the Happy Mac appeared. I "reflashed" the ROM from a Linux box and it worked fine after that.
At the very least you'd need to make some kind of adapter circuit.
