Two systems running as one

I have two laptop computers I would like to run in parallel. Essentaily I would like the resources of two computers available through one interface, seamlessly. Is that possible? Their both running Win98, and have extreemly simular specs. Also I would pref do it w/o a network card, but do have one available for both.
Any help would be appreciated, even if its just a link to directions, because I'm sure this has been covered before. Thanks

 

Perhaps I should explain what I plan to do with these. I want to play videos and music, from both hard drives, and have the same image/ desktop displayed on both screens, while only actually interacting with one computer. This would be alot easier with a desktop, the dual display thing is whats gonna get me, I think.
