  Re: Sign of center pin on power adaptor
 
(...) It's the same PSU as used for the 9V train controllers. (17 years ago, 10-Jul-07, to lugnet.robotics.rcx)
 
  Re: Sign of center pin on power adaptor
 
(...) The wall wart for my RCX says "output 10.8VAC 700mA 8w" so it sounds like the rectifier is in the RCX, not the wall wart. (17 years ago, 10-Jul-07, to lugnet.robotics.rcx)

  Re: Sign of center pin on power adaptor
 
(...) I once came across a box full of old wall wart power supplies at a rummage sale and after digging through it for 10 minutes or so I found three that had 12V AC and the correct plug for the RCX. They work perfectly and I think I paid about $1 (...) (17 years ago, 10-Jul-07, to lugnet.robotics.rcx)

(...) 9V (orientation doesn't matter). But I wouldn't recommend it as there have been reports of burnt out rectifiers from people doing that. Hope this helps, ROSCO (17 years ago, 10-Jul-07, to lugnet.robotics.rcx)
 
  Sign of center pin on power adaptor
 
I am looking for the sign of the center pin on the RCX 1.0 power adaptor plug. I have a DC 9v 200ma transformer and want to plug it into the RCX but I do not know what the sign is on the center of the plug. It looks like the rush on buying the old (...)

  Re: Is there a usable Mac OS X version?
 
(...) I think John Hansen actually made a pbForth terminal in NQC. My RCXTcl works on a PC, but I never did get around to packaging it for Macs. Probably because I don't have one myself :-) That being said, once you have a terminal program to talk (...) (17 years ago, 28-Jun-07, to lugnet.robotics.rcx.pbforth, lugnet.robotics.rcx.nqc)
 
  Is there a usable Mac OS X version?
 
Is there a usable version of pbForth for Mac OS X and the USB tower? I have NQC, so there should be no trouble downloading firmware, and Mac OS X has good terminal software, but how do I set up things so that terminal communication goes via the USB (...)

  Re: lcd display on RCX 1.0
 
(...) If you load RCX2 firmware in a RCX1 brick (they are fully compatible*), you'll have acces to this function (and all other RCX2 specific possibilities) Philo *Except for some minor differences in IR hardware. (17 years ago, 25-Jun-07, to lugnet.robotics.rcx.nqc)
 
  lcd display on RCX 1.0
 
NQC: with RCX2, it has a function to display a user defined value. Is there a way to do it with RCX 1.0? How about just to display the current mail value with RCX1.0? Suggestion? Thanks in advance. --Elizabeth (17 years ago, 24-Jun-07, to lugnet.robotics.rcx.nqc)
 
  Re: Shutdown/Off while program running crashes BrickOS

  RE: IR Problems
 
Elizabeth is quite right. It's easy to get collisions on the IR "bus" if two devices are sending (or replying) simultaneously. What I've done in the past with two RCXs is define one RCX as primary that is periodically (every 100 to 250 milliseconds (...) (17 years ago, 2-Apr-07, to lugnet.robotics.rcx)
 
  RE: IR Problems
 
RCX IR does not require direct line of sight. All sorts of reflections will work. Especially if you're in a "smallish" (bedroom, home office) room. The RCX firmware always has the IR turned off. "Wait for mail" and "send mail" is just a higher (...) (17 years ago, 2-Apr-07, to lugnet.robotics.rcx)
 
  RE: IR Problems
 
IR communication is no where near the reliability like a tcp/ip. You can easily lose a message ... so program must be either extremely simple one way communication. The sender should be programmed to handle message loss. What I had the kids done was (...) (17 years ago, 2-Apr-07, to lugnet.robotics.rcx)

The 1.0 is just to the side of the tower. I think my problem (...) (17 years ago, 2-Apr-07, to lugnet.robotics.rcx)
 
  RE: IR Problems
 
Are you sure your problem isn't interference? How did you "lock out" the RCS 1.0 from receiving (and responding) to the direct commands? You have two RCXs turned on and sending direct commands from the PC. They will both try to respond to the (...) (17 years ago, 2-Apr-07, to lugnet.robotics.rcx)

I have been running RoboLab 2.54 B on a Dell Inspiron 1100 with little problem until of late.

I also figured out what COM3 was: the internal modem. I disabled it in Device Manager and now the only port that I can find in my C# app or in Hyperterminal is COM1, the serial port.
