Okay, I got it working. Here's the short version of the problem: I installed the RCX 1.5 software on a WinXP machine with 1GB of memory. The installation went fine. When I tried to run the program, it beeped and hung with a blanked screen. After (...) (17 years ago, 9-Dec-07, to lugnet.robotics.rcx)
