Forgive me while I think out load here. I'd like some feedback on some goals and ideas I've thought of for a new bytecode interpreter. Any critiques, comments, opinions, recommendations, or additions are welcome: I would hope that the new system (...) (25 years ago, 8-May-99, to lugnet.robotics.rcx)

(...) In environments which provide general purpose pointer types which can be assigned to addresses of explicitly allocated memory (like C and C++), garbage collection becomes an NP-hard problem. In environments which have no end-user accessible (...) (25 years ago, 8-May-99, to lugnet.robotics.rcx)

I'm following with great interest the discussion about a new firmware for the RCX. When the discussion started, I expressed some opinions about staying as much compatible as possible with the official firmware. Now, after a second thought, I realize (...)

(...) Hmm: - I believe that, after main starts, unless you press IN_3 *very* quickly, that IN_3 will not be 1, hence stop wb will be chosen. Perhaps you want something like this? : task main { while (true) { wait(IN_3 == 1); // start motor wait(IN_3 (...) (25 years ago, 7-May-99, to lugnet.robotics.rcx.nqc)

(...) I believe transmission and reception are independent, i.e. the emitter circuit is decoupled from the receiver circuit. The hardware on the H8 is full duplex. Once you finish sending a byte, I think you get two interrupts: one saying a byte has (...) (25 years ago, 5-May-99, to lugnet.robotics.rcx.legos, lugnet.robotics)

I succeeded in using (emulated) floats in a legOS program. Here are some instructions in case some of you want/need to try 32 bit FP emulation. First of all I must point out that I have no merit at all in having got this result, a part from having (...) (25 years ago, 5-May-99, to lugnet.robotics.rcx.legos)

Here's the fair play policy: (URL) right. The Lego Group is exceedingly protective of their trademarks and intellectual property. If they haven't pursued action against legOS, it's very likely a deliberate policy rather than an oversight. Jonathan (...) (25 years ago, 5-May-99, to lugnet.robotics.rcx.legos)
