Artifacts, Chapter 7

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.
Do you have Microsoft ACCESS on your machine? If yes, take a look at Temp/DCHSLegacyCatalog20240416.accdb, we are seeking a volunteer to develop scripting for on-line use of our artifact database at the Lawshe Memorial Museum in S. St. Paul, MN. Comments or queries to la.gj.benson@comcast.net

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 Canadian Patrol Frigate (CPF) ship model (right) 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 Dennis 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"! In the 90s, the U.S. Navy began replacing the CP-901s with CP-2044s - an embedded microprocessor machine developed by Unisys.

2. Hardware: Printed Circuit Cards, Memory, & Power Supply

2.1 Printed Circuit Cards

We at UNIVAC...Unisys designed quality into machines by disciplined design rules decades before industry developed ISO 9000 standards, for example for 15 pin cards in the 50s we used 'germanium' standards.

2.2 Memory Hardware

At the left is a rotating magnetic drum model 1119A. In the center is rotating magnetic drum model 1124G1. At the right is a rotating magnetic drum model 1124A. These three drums are at the Lawshe Memorial Museum. One came from the estate of Harry Wise, the other from Donald Anderson.

Below left are some film memory layers - at the right is a core memory plane:

This is a 6" x 9" printed circuit card holds Randon Access Memory (RAM) chips. At the right is a Bubble Memory component, used for a Coast Guard project and a NAVAIR airborne project.
