Looks like I bypassed the mail list with this one...

I tried this myself and didn't have any trouble.  That was on a P123 and
RTL V1.0  For a while there I thought I had a problem with the timing
accuracy but it ended up being my power supply not being able to handle
the load of the servos.

At the time I thought that this would make a great RTL advocacy
project.  Take the linux router project as a base and add rtl for a
single disk demo that would control a couple of servos via TCP/IP &
parallel port eg robot arm or walking robot.  It would be a little like
the zentropix RTL weather demo disk but a little more interesting.

Anyone interested?

Stuart Warren
