I have a Dell Dimension 8200. About 3 years old. I am not ready to buy a new computer yet. It works fine, however I would like to have another memory chip. I called Dell and they told me that this system was shipped to me with 1 512mb chip. The dimension apparently used very expensive memory. I do not have the exact number. I was making an inquiry as if anyone out there may have a USED chip CHEAP or a whole 8200 computer that i could buy as a parts machine?? Please send your response direct to my e-mail address as i can never find answers here after I ask a question. Thank you all. Thank you all, but i have already checked. Even Tiger Direct wants over $250.00 for it. I just want something to hold me over until i buy a new computer. Thanks again.
