(...) Now that is conveinient! ;) (...) I am messing around with this idea hoping to get the gear ratio I want (2:5). I currently have 16t on the motors driving 40t on the drive axle.

  RCXCC and Visual NQC 2001
 
It's been a while (since 2001) that I have not used NQC. =0 I tried installing RCXCC on windows XP and it won't work. =( Not compatible I guess. I tried to look for Visual NQC 2001 on the net but can't seem to find it either. =( The main website no (...) (21 years ago, 13-Feb-04, to lugnet.robotics.rcx, FTX)
 
  Re: where leJOS firmware ?
 
(...) In RAM, as specified. RAM will hold onto the data just fine, as long as you supply power to it. And the RCX RAM is powered, via battery (that's why if you remove the batteries, you loose the firmware... and everything else). (21 years ago, 12-Feb-04, to lugnet.robotics.rcx.java)

  Re: Controlling events
 
(...) You can use events with a 1.0 RCX, but only if you load the 2.0 firmware into it. Download the FIRM0328.LGO firmware file instead of the FIRM0309.LGO file before you load your NQC programs into the brick. The newer firmware was supplied with (...)

  Re: where leJOS firmware ?
 
(...) The 32K RAM in the RCX is powered by the batteries even when the RCX is turned off. This is why the firmware (leJOS or otherwise) does not get erased when you turn the unit off. But if you remove the batteries for a few minutes, it does get (...) (21 years ago, 12-Feb-04, to lugnet.robotics.rcx.java)
 
  where leJOS firmware ?
 
Hi everybody. I'm trying to guess where exactly the leJOS firmware is stored. All domcuments i've read say that it's in the 32K RAM. But i ask my self why they say RAM; if you turn off the RCX neither the firmware or the user programms doesn't (...) (21 years ago, 12-Feb-04, to lugnet.robotics.rcx.java)
