I'm working on a syntax highlighter for H8 assembler for BricxCC. I downloaded a couple PDFs from Hitachi's website. I have the H8/300 Programming Manual (e602025_h8300.pdf) and THE INTRODUCTION OF HITACHI H8 MICROCOMPUTERS (introduction_h8.pdf). (...) (23 years ago, 18-Mar-02, to lugnet.robotics.rcx.pbforth)

Hi Chris, Thanks for the input. This is the kind of information I need. I have always relied on alcohol as a cleaner for contacts and I did not think of the effect it might have on the rubber contact. I thought the button might be a carbon contact. (...)

You have to wonder how the SDK could possibly do that. The only opportunity I can see for it doing this is with the binary files javac and java, but I doubt they have auto-update features. Maybe the applet JVM has this? p.s. Kudos for reading the (...) (23 years ago, 18-Mar-02, to lugnet.robotics)

You may also be able to return them to Lego for free and get replacements, it depends on how old they are. I would try before you have to buy a new motor, they aren't the cheapest. Andy ----- Original Message ----- From: "Benton Jackson" (...) (23 years ago, 17-Mar-02, to lugnet.robotics.rcx.legos)

Jeremy, The motors that come with Mindstorms are geared internally, and it's probably jammed gears that are causing you woes. Your "friend" gave you some broken motors. I've never taken one apart-- it snaps together in a way that looks easy to break (...) (23 years ago, 17-Mar-02, to lugnet.robotics.rcx.legos)

After many headaches, I finally got legOS 0.2.5 running on RH 7.1 and am able to compile and DL programs to the RCX. There is one odd thing, however - of the (...)

Hey, I just discovered that my 3Com HomeConnect USB camera is extremely Lego-compatible. It's so close I have a feeling it's not an accident. I built a very nice pan-tilt mechanism for it. What fun!
