The real IBM PC and XT computers did not have a real time clock built in.
There were a number of third party cards that were available that provided
a RT clock as well as the stuff already talked about. Some of the clones
though did have a real time clock built in along with the associated
battery. The HeadStart is one that comes to mind, and I *think* the Leading
Edge Model D was another.
