Artifacts Chapter

Webster defines ARTIFACTS as "An object produced or shaped by human workmanship; especially, a simple tool, weapon, or ornament of archaeological or historical interest."
For our Legacy, we've identified artifacts as 'historical interest' publications, hardware, photos, web and other objects which document or illustrate our history. As we have been collecting these objects - they are catalogued and donated to either the Lawshe Memorial Museum or to the Charles Babbage Institute.
The sections below are a bit incomplete as we take snapshots of contributed items then get the pictures linked.  Note that trinkets, plaques, awards, and desk top items pictured in the Mementos Chapter may not be kept because storage and display space at the museum is limited. After photo's are made and digitized, some objects are returned to the donor.

Models

The first models contributed to the Legacy project were the NTDS computer family models shown at the right from Lowell Benson. In the late '80s, he rescued these from a marketing office in Red Bank NJ, which was being closed. These are now at the Lawshe Memorial Museum.

The Computer's chapter has a table which identifies and provides characteristics of these ruggedized Navy and Marine computers.  Left to right these are:

AN/USQ-17 CP-642A CP-642B CP-667 CP-789 CP-808 CP-848 CP-855 CP-890 AN/UYK-7

This CPF ship model [Canadian Patrol Frigate] was donated to the Legacy project by Dave Kolling. Refer to the Systems, International chapter for the system development story. As part of this system, we developed a manufacturing and engineering support facility in Winnipeg. Search for SHINPADS or AN/UYK-502 or Abbot to find more of the stories about this system.

The P-3C airplane model came from Jim Rapinac. The original computer aboard this Anti-Submarine Warfare Lockheed aircraft was the CP-901 that had a 25 year production run and a 45 year operational life. Refer to the Systems, Airborne chapter or to the People, They Flew chapter to learn more. Or read the book "Hunt for Red October"!
