The Columbia VP was another Compaq Portable like IBM PC compatible from 1983. It was built using a very rugged metal case and sported a larger internal monitor then the Compaq. This, of course, made it much heavier.

Yes, the system really is as dirty as it looks. I didn't get a chance to clean it up and I figure the dirt is probably protecting the paint anyway.

The machine is actually in really good condition regardless of the dirt since there are no scrapes, dents or dings to speak of.
