They started by first writing the user's manual for the product.

A 2002 Boston Globe article refers to Koplow as a "wisecracking rebel" who "was waiting for dismissal when, in 1975, he developed the product that made computers popularly accessible." In Koplow's words, "Dr. I, along with Dave Moros was relegated to Long Range Planning — 'LRPed'. was tantamount to being fired: 'here is a temporary job until you find another one in some other company.'" Although he and Moros perceived the assignment to design a word processing machine as busywork.

The rudimentary Wang 1200 machine was the precursor of the Wang Office Information System (OIS), which revolutionized the way typing projects were performed in the American workplace.

Following the Wang 1200, Harold Koplow and David Moros made another attempt at designing a word processor.

The calculator was right, the printed tables were wrong, and the company's reputation was made.

In the early seventies, Wang believed that calculators would become unprofitable low-margin commodities, and decided to exit the calculator business.

The 200 and 300 calculator models were available as timeshared simultaneous (SE) packages that had a central processing unit (the size of a small suitcase) connected by cables leading to four individual desktop display/keyboard units.

Competition included HP, which introduced the HP 9100A in 1968, and old-line calculator companies such as Monroe and Marchant.

Compugraphic retained the rights to manufacture the Linasec without royalty.

Using factor combining it was probably the first desktop calculator capable of computing logarithms, quite an achievement for a machine without any integrated circuits.

The electronics included 1,275 discrete transistors. It actually performed multiplication by adding logarithms, and roundoff in the display conversion was noticeable: 2 times 2 yielded 3.999999999.

Wang's first attempt at a word processor was the Wang 1200, announced in late 1971, but not available until 1972.

The design consisted of the logic of a Wang 500 calculator hooked up to an OEM-manufactured IBM Selectric typewriter for keying and printing, and dual cassette decks for storage.
