Here is what I mean: Power PC 8 or 16 MB of RAM ( want to use those SIMs I had to buy for my last desktop computer) Input for Video (like a quickcam, could even stay (...)

Is there any way to turn off IR decoding? I see in the library file that PWM and LCD printing can be turned off. Thanks. -John (29 years ago, 12-Feb-96, to lugnet.robotics.handyboard)

Now THIS is weird. The battery light status seems to depend on the light going to the Sharp IR sensor now!!! If I expose it to light, the battery light turns on. If it's dark, it turns off. Modulated IR light makes the batt light flash. Have I (...) (29 years ago, 12-Feb-96, to lugnet.robotics.handyboard)

IC users, I was thinking of perhaps porting as11_ic to the mac and I think I understand exactly what is going on in the unix script except for one thing. What is the C preprocessor doing?
