[1][2] Kyriakides had previously founded Lexicon Corporation of Fort Lauderdale, a maker of telecommunications equipment for mainframe computers, in 1976, selling it off in 1979 after it had gone public.

Based on Intel's 80186 microprocessor–microcontroller and compatible with NEC's MultiSync monitor, the ADA could display color graphics at a maximum resolution of 800 by 600 pixels.

[9] In December 1986, Kyriakides relinquished 32 percent of his shares in Mylex to an investor group led by M. Akram Chowdry, chairman of Prime Circuit Technology of San Jose, California.

[13][14][15] Mylex's motherboards did not sell very well, and by 1991 the company's large inventory of unrealized i386 and i486 processors were rendered obsolete, contributing $800,000 to a $1.2 million net loss in the third quarter of that year, based on diminution of the chips' value combined with the cost of warehousing them.

[15] Sales of their motherboards remained stagnant into 1993, at which point the company began looking at other segments of the personal computer market.

[16][17] In 1993, the company began its pivot to designing and selling RAID controllers and LAN management software to appeal to the file server and workstation markets, finding much more success here than in their earlier ventures.

[20] BusLogic's acquisition was finalized in late January 1996, its shareholders netting additional stock options post-acquisition, increasing the terms of the sale to over $67.9 million.

[26] IBM's divestiture of Mylex was completed in December 2002, its assets and its eight remaining employees in Boulder being absorbed into LSI's Logic Storage Systems division based in Tucson, Arizona, that month.
