Will the Dell 2001FP work for me?

[MrTop]

I have a Compaq Presario 2500 Laptop with an ATI Mobility Radeon 64 MB (I think) video card. I plugged an older CRT in and it worked at 1600x1200, but was abit blurry, but I'm contributing that to the fact that the CRT was old. It would be nice to have PT on the small screen and 4 full tables on the Dell [img]/images/graemlins/smile.gif[/img]

Also, I only have 256k of memory, which I want to upgrade. Can I add a 512 stick in the empty slot? Or does it have to match the other?

Thanks for any help that you can provide.
