"Design Systems" and phone number 212-995-8494 - sellers of hardware and software, to Maya Video Products, Inc., 148 Madison Avenue, New York, N.Y.

I found a Mara J. McGinnis, who is 41 years old, married to Karl Bauer in 2009, and who has been employed at Pratt Institute since, at least, 2006.  She is, according to the Pratt website, "Executive Director of Communcations and Marketing", in Myrtle Hall.  She has, most importantly, the same phone number, at her home address, that was entered on a fax from "Design Systems", from someone named "Jonathan", to me, in December, 1990, at Maya Video Products, Inc.  That home phone number is 212-995-8494, and, her home address is:  185 West End Avenue, Apt. 23b, New York, New York  10023-5549.  She has lived in Buffalo, N.Y., Rochester, N.Y. and Scranton, Pa.  She was a writer for the University at Buffalo, The State University of New York, in 1998.  Two articles she wrote are about:  2 Professors are appointed Distinguished Professors; and, the President of the Federal Reserve Bank of New York to give a lecture:  https://www.buffalo.edu/news/releases/1998/06/4236.html
and

I found a few companies that could be "Design Systems" in 1990, where "Clem" and "Jonathan" worked.  One is located in Williamsville, N.Y.. and, another is located in Dix Hills, N.Y.   The Dix Hills location was filed as "Design Systems of New York, Inc." on August 6, 1987, in Suffolk County, N.Y., with entity address:  "Seth Steinberg, 6 Lauren Avenue South, Dix Hills, New York  11746".  This is an inactive company as of September 29, 1993.

The Williamsville, N.Y. location was filed as "Design Systems Collaborative, A Bissell, Leslie P.C.", on October 7, 1983, in Erie County, N.Y., with entity address:  "Bradlee W. Townsend Esq., 22 Evans St., Williamsville, N.Y.  14221".  This is an inactive company as of March 25, 1992.

Who are "Clem" and "Jonathan"?  I was told that was their names, when I sent and received the fax, and, talked on the phone.  I was told, though, that the chair file that I was sent, on a disk, was one of many, if I wanted any other chairs, on the phone.  THE TRUTH OF THE MATTER IS THAT I WAS SENT AN AUTODESK CHAIR CREATED FROM AN AUTODESK FILE, WHICH WAS PART OF THE AUTOCAD PROGRAM.  I WAS NOT GIVEN ANY BOOK OR INFORMATION ABOUT THE HARDWARE AND SOFTWARE THAT I WAS USING, AND, I WAS TOLD EVERYTHING WAS NEW.  THE SELLER OF THE SYSTEM TO MAYA VIDEO PRODUCTS, INC. WAS "DESIGN SYSTEMS".

The other two "Design Systems" are:  "Design Systems, LLC", filed January 3, 2005, with entity addres:  363 Canal Street, 2nd Floor, New York, New York  10013;  and,  "Design Systems Group", filed August 15, 2011, in the New York County of California, with entity address:  2604 3rd Street, San Francisco, California  94107, with Sue LaBouvie as Chief Executive Officer.  These are both active corporations with no Registered Agent.  The N.Y. Secretary of State lists these businesses, today.

"Design Systems Group" is a Foreign Business Corporation, ID# 4130895.  The others are Domestic entities.

At this 185 West End Avenue location is another business called "Revesz International LLC" and http://globalreach-radio.com/ .   Could this be the same "Design Systems" that existed in 1990, but, now, existing under a different name?  This company came up when I did a Google search for "Design Systems, New York, New York, 212-995-8494".
