pc100 16 chip 256 mb laptop ram

Hey , does any body have or know where I can get a couple sticks of pc 100 16 chip 256mb laptop ram ? I have an old laptop that I received from a relative before they threw it away. It is a Dell inspiron 3800 pentium 3 @600 MHz. It only has 128 mb ram , and I increased the virtual ram to 512 mb . Its max ram capacity is 512 mb or 2x 256 mb
hope someone can help. It doesnt have to be brand new ram.
