How do I visit youtube mobile website on desktop?

My Windows 98 computer is too old to handle the desktop youtube website. I used to always go to m.youtube.com because my computer handles it just fine. but now it sends me to www.youtube.com whenever I go to the mobile website. I'm using Opera web browser 10.10 and can't upgrade to never versions of any web browser to get add-ons to send me to the mobile web. Is there any way for me to get to the mobile website?
