I'm a dummy when it comes to hardware: I have a couple castoff PCs. Both PIIIs, 450MHz and 800MHz. Both are woefully low on memory. They have PC133, 128MB modules. I haven't found info on either on the net. One is a Dell, but they don't list that model for upgrade info. Question: Can I put 512MB modules in them? -- Jim Sabatke Hire Me!! - See my resume at http://my.execpc.com/~jsabatke Do not meddle in the affairs of Dragons, for you are crunchy and good with ketchup. NOTE: Please do not email me any files with the following extensions. They are deleted on my ISP's server before I ever see them, and no bounce message is sent. I am not notified they are deleted. I am doing this because of the volume and size of spam files I receive. If you wish to send me a file of one of these types, contact me first and I will tell you how to send it: lnk asd hl |ocx reg bat c[ho]m cmd exe dll vxd pif scr hta jse? sh[mbs] vb[esx] ws[fh] wav mov wmf
