PC100 in an older laptop?

[Scott Tiger]

While I've heard it's usually okay to put PC100 in a desktop that's designed for PC66 is the same true for a laptop? I have an older Compaq Armada (P2, 333) that was designed for PC66 and that stuff is pretty scarce right now. I can get 128 meg sticks of PC100 made by Crucial or Kingston for about half of what PC66 is going for if I look around on Ebay. Is this workable though?

The same applies as to wether or not the chips are compatable.

I tried putting some PC133 inplace of some PC100, didn't work.
