AHHHH link is dead... Well that was in 2012 (now 2019) , I am sure it did work once. It redirected, I will see if I can pull anything I can use from that. Thanks!
Sample output on my 1941 router:The number shown is 1917381 +/- 10%. Which would imply a clock rate of 2000000. My answer is a little late to the party, but maybe this will help the next person as the existing answers did me.
