On a slightly related note, I've been trying to get all this to work via Linux on a PowerBook FireWire.

(...) "no reply from RCX" is probably not an adapter problem. My first guess would be that the RCX doesn't have firmware loaded (If you see "00.00" on the display, firmware is loaded, if you just see an icon and "1", then it isn't). Second guess (...)
