Hi, I saw a posting on lugnet from a year ago that you were working on an H8 emulator. Are you still working on it? I need an emulator for the processor for a class I'm teaching... Any info would be great! Thanks, Jason (22 years ago, 11-Dec-03, to lugnet.robotics)

Steve, Thanks for the info! I've placed an order for the US sensor (well, a pre-order, as they say they'll be shipping orders out only around Jan.2004). They are a little expensive though, I must say. Is this sensor easy to control when programming (...) (22 years ago, 11-Dec-03, to lugnet.robotics)
