I don't know the answer to this - but if your son is 'into' programming
and computers, you could consider just dumping the Lego software and using
NQC. With the Lego environment, you get to "program" by dragging cute little
icons around - and that's what needs the high speed computer. But with NQC,
you write programs as text files (just like "real" programming) - and you
could do it on a 1MHz Z80 - a 200MHz machine is overkill!
The *big* problem with older machines is if you are running Win95 which
doesn't have USB drivers.
You should definitely try downloading the RCX firmware and a simple test
program to be sure that it's all going to work for your son - but if you got
the firmware to download, it's probably all OK and the annoyingly slow
response time is your only problem.

I don't recall anyone having problems with the new USB tower. The old
serial port tower had this burnout problem with (IIRC) Win2k which was
doing something strange with the RS-232 control signals.

I've never had this problem - but it's certainly possible in theory.
You might want to try the 'range' switch on the tower - switching it
into the other position sometimes helps.

Get NQC - if you can write C programs you'll prefer it to the Lego environment.
(NQC is a free download).
