Hi , you know the story, guy collects cool old stuff, keeps it around till he feels like tinkering with it, maybe giving it to somebody to use, but instead it collects dust and space, and then guy meets girl and girl moves in, sees these "space stealers" and says they gotta go! So my loss is your gain! I dont have the full specs of these machines, but do know what is included and what is not... Black Compaq Presario - Ah an orginal machine that was purchased at once known as "Circuit City" this machine is complete but missing back screws to secure cover. I tried to run it a few times, no luck problem with floppy drive but boots fine to compaq screen and system bios. No usb or ethernet but onboard dial up.. Compaq Prolinea 575 - This machine is also complete with thunb type screws to the cover.I tried to reinstall windows 98 on it back in the fall, but came with few errors. probably a bad installation disk. Has ethernet card, but no USB ports. Compaq Deskpro - this one was with me for quite some time and was personally used until I decided to tinker with it, took it apart, stopped at one point and forgot all about it. This does have usb ports but no ethernet. It is missing hard drive, CPU processor, and memory. I do also have several peices, parts and misc plugs, hard drives, wires, CPU's and memory that I could also throw in if you wish I have not gone through that stuff yet, but if you say you'll take all the parts and these 3 desktops along with it, I'll be sure to have them ready as it;s time for me to find new hobbies that do not take up space! email is preffered and local delivery / pick up only.
