(...) Just scanned through Kekoka's excellent dissection of the ROM routines. Seems like system variable/register at address $ff7b contains the relevant Long range/Short range bit flag, ie. bit 0 toggles the IR range 0 = Long, 1 = Short. Could I (...)

Wes, relays would work pretty well. (Still, how much current do your motors draw???) The LEGO motors draw about .35 Amps (350 Milliamperes) You could connect two 5V coil relays , each with a diode in series with the coil, connected oppositely to (...)

Hello, Is it possible to use a PC's IR port, instead of the IR tower, to communicate with an RCX? (I have a Dell Inspiron 3500). -- Brad Aisa baisa@NOSPAMbrad-aisa.com -- PGP public keys available at: (URL) faire." (25 years ago, 9-Nov-99, to lugnet.robotics.rcx)

(...) These solutions bring up problems of their own: using a motor to operate a switch (battery box or Lego switch) requires monitoring the switch state to determine on/off status.

I'm afraid these are the same errors that were reported with 0.2.1. It would appear that it is looking at a very long and convoluted path which happens to include the standard gcc, not just the cross-compiler. But that is just a guess based on a (...)

That's me, trying to use legOS 0.2.2 on WinNT with CygWin. I'm using the same tools that worked for me for legOS 0.1.7.
