The first GDS system was shipped in late 1971 to Intel. The growth of sales of GDS paralleled that of the nascent integrated circuit industry. By August 1976 there were 121 GDS systems installed at 70 companies including many Fortune 500 corporations including Motorola, International Telephone & Telegraph, Fairchild Semiconductor, and others. Of these, 43 were installed outside the U.S. In 1978, Calma, which never had a public stock offering, was acquired by United Telecommunications, Inc., (UTI) of Kansas City, Missouri, for $17 million in stock. Calma became part of UTI's United Computing Systems (UCS) operating unit. UTI took a hands-off approach to managing its acquisition, allowing Calma to continue largely unchanged on its growth path. In 1978, Calma introduced GDS II (pronounced "G-D-S two"), a modernized replacement for GDS. With its 32-bit database, GDS II met the need for greater capacity and resolution in IC designs. GDS II quickly replaced GDS as the data entry system of choice for many IC design groups. By late 1980, there were 171 installed GDS II systems. In December 1980, the sale of Calma by UTI to General Electric (GE) was announced. The sale price was $110 million, with an additional $60 million contingent on Calma's profits over the next five years. The acquisition was completed on April 1, 1981. GE had grander designs for Calma than had UTI. In addition to the hope of maintaining dominance in the IC market, GE aimed for Calma to expand in the architectural, engineering, manufacturing and construction markets – "factory of the future" was a prominent slogan. Due partly to a mass exodus of talent after GE moved its own people into key management positions, partly due to excessive expectations, the changing nature of the market and the inherent difficulty of keeping up with rapidly changing technology, these ambitions went largely unrealized. Beginning in 1988, GE sold Calma. The electronic side of the business was sold to Valid Logic Systems in April 1988. (Valid in turn was acquired by Cadence Design Systems in 1991). The remainder of the business (mechanical/architectural) was acquired by Prime Computer in a sale completed in January 1989. Prime had just completed a hostile take-over of Computervision. Prime basically merged the Calma Mechanical and AEC product lines with Computervision. Computervision, including the Dimension III product, was acquired by Parametric Technology Corporation in 1998.
