I was wondering if there's a freeware version of IC for windows 95. If
so, how can I get it? Also, do I need any registration number? Please
respond asap. I'm anxious to program my HB.
Thanks,

| Heres a IR xmitter/receiver idea for you; I've seen this approach used in equipment and it works very well, I'm not sure how well it will work for robotics but believe it can be adapted. This is difficult to explain but easy to build, so hang with (...) (28 years ago, 3-Mar-97, to lugnet.robotics.handyboard)
