Is the firmware still installed on the RCX? When you turn it on if it
just shows a single digit, then there isn't any firmware. With firmware
loaded you should see something like "00.00!1" where ! is the LCD icon
of a person.
If firmware is not installed, then download the firmware (either with
Bricxcc or NQC directly).
If firmware is installed, from a console window try:
nqc -Susb -v -raw 120000
and post (or email me) the results. Also check to see if the green LED
on the tower lights up while this is happening.
