I recently bought a RIS 1.5 with brick 1.0 and serial tower (no CD). I got a cheap USB adapter and installed the RIS 2.0. It worked almost fine for a few days. Everytime I started RIS I had to autoconfigure tower, which used COM2. I had to try two or three times to download programs, but it worked.
Later, I installed Bricxcc and connected as well, although I downloaded no program. I did download the original lego firmware with Bricxcc and since then RIS is not able to connect to the RCX.
I have tried with new batteries, uninstalling Bricxcc and then RIS. Installing RIS again, with reboots in the process. Nothing seems to have changed. I cannot connect.
Any previous experience?
I was thinking about buying an USB tower, but I don´t know if it will work with RCX 1.0.
Thanks for your help
