I have installed correctly the RIS 2.0 in an old laptop running Windows XP and I successfully downloaded the firmware through the RIS 2.0 to the RCX 1.0, following the standard setup instructions.
Now when I turn on my RCX 1.0, the display shows the full function mode. I can also change the activated sensor port and the outputs pressing the View button. Yet, the Prgm and Run button do nothing.
I cannot change or run any program. It stays in program 1, which does not run when I press the run button.
I would appreciate any help please.
