I've got a T1000 LX lying around. That can't be more than 9MHz. My main machine is 50MHz, a Toshiba Satellite Pro. Runs a very hacked kernel with wifi support. These computers will run forever. (It's sad that these computers do me just fine, but I still shovel out cash for new computers for the purpose of viewing websites and playing games- both of which just waste time.)
last month i had a client calling me for problem with his windows 98... well np, i got there start the pc... wait wait wait, ... untill i found out why, it was a Pentium 166mhz... what a painfull souvenir!
