I still have my IBM XT. I think it's 1979 or 1980. It running speed is 2mb. The 286 was 16. That was when you had to know all the commands to have it get you anywhere, doing the old C:/ prompts and stuff. No internet connection as it wasn't available at that time. Had 5 1/4" drive. Could hear the fan running from the other room. I don't think the trash man waould evern take it, still up in the attic. It has one of the first color monitors a CGA (color graphic adapter)
