[2][3][4][5][6] The Hercules Graphics Card included a "Centronics compatible" parallel printer port, the same as the IBM Monochrome Display and Printer Adapter board that the card was based on.

An acquisition of Hercules by German graphics card maker ELSA fell through in 1998 after the companies could not agree on terms.

The Hercules brand was acquired by the French-Canadian based Guillemot Corporation for $1.8 million.

Also in 2000, Guillemot introduced a new sound card, Game Theater XP, with the Hercules brand name, and Hercules gradually became the computer peripherals brand in Guillemot Corporation.

Within the Guillemot group, computer peripherals (audio interfaces, speakers, webcams, networking) are designed by the Hercules division and given the Hercules brand, while game peripherals are designed by the Thrustmaster division and receive the Thrustmaster brand.
