FOREWORD
This addendum updates spec language to reflect current technology, to prevent tying the spec to a particular technology, and to make the spec more maintainable as the technology progresses. Specifically, it makes the processor generic by removing "Intel," eliminates the requirement for a 3.5-in. disk drive, adds some hardware requirements, and adds brackets as a reminder to the user that bracketed values should be carefully considered and specified according to the project's needs.
Note: In this addendum, changes to the current standard are indicated in the text by underlining (for additions) and (for deletions) unless the instructions specifically mention some other means of indicating the changes.
