Commodore 64 came in a relatively close cousin of the venerable Compaq or Kaypro. It had a COLOR 5" screen a built in keyboard (which, by the way, had a lovely touch) and a single disk drive. Back in the day, as some of us old fogies recall, these non-hard drive computers came with a 5" floppy drive and if you wanted to really pep it up, you could "daily chain" a second drive to the first drive. The program ran on the first drive and that data ran on the second. This portable Commodore could only do a single drive so did not sell very well. And it weighed about 25 pounds. Portable my ass!
