  Problems with RCX Robolab and PowerMacs 6400/200 and 5500/225
 
Hello, I'm teaching an RCX-based programming class using the Robolab software to a group of 19 4th,5th and 6th graders. I've been trying to get the Robolab software installed and running on the Powermac 5500/225s and 6400/200s owned by the school. (...)

I'm a user, not engineer, but.. you might want to try this if you haven't already. I had the same difficulty and went through all the toubleshooting methods you have. This is going to sound silly, but has worked for me: With the IR tower on low (...) (25 years ago, 20-Nov-99, to lugnet.robotics.edu, lugnet.robotics.rcx.robolab, lugnet.robotics.rcx)

You could try using NQC (or MacNQC) and see if it works any better. I know in the long run you want to get Robolab working, but testing MacNQC would at least separate a Robolab-only problem from more general problems (serial port problems, cables, (...)

Paul, I've snipped all of the text about how RoboLab and the Mac might not play nicely together. I have had great results with my own system at my office, and then when I did the tutorial at MIT, things failed miserably. I turned off the large (...)

I had a similar problem and suggested used the three cable method you mentioned with great success. Before I tried this I sent an inquiry to Dacta and got this response "There is an issue with some Macintosh serial ports that we are currently (...)

I believe Fred Martin ran into similar problems and the serial extension did indeed help. I think his write-up of the issue is somewhere on his site: (URL) Baum (...) (25 years ago, 3-Jan-00, to lugnet.robotics, lugnet.robotics.edu, lugnet.robotics.rcx.robolab, lugnet.edu, lugnet.robotics.rcx)

Hello to all, Thanks for all those who wrote in with suggestions for how to get my RCX bricks to work with the PowerMac 5500s that I was having trouble with. Here's a summary of my experiences and how I eventually got enough working machine to teach (...)

Thanks for the reply, I really enjoyed your book. My son (age 13) also enjoyed it. He's starting out using ROBOLAB, but your book has sparked an interest in C (like) programming. I look forward to a sequel. (...) (25 years ago, 6-Jan-00, to lugnet.robotics, lugnet.robotics.edu, lugnet.robotics.rcx.robolab, lugnet.edu, lugnet.robotics.rcx)
