Video chips
Chips and Technologies was the first company (outside of IBM) to deliver an EGA-compatible chipset. The Enhanced Graphics CHIPSet consisted of the four chips:
Later C&T announced a "Super EGA" dual-chip chipset: 82C435 Enhanced Graphics Controller and 82A436 Bus Interface with resolution up to 800×600 38MHz.
C&T was the first company (outside of IBM) to deliver a compatible VGA chipset, the 82C451, and VGA cards were introduced the same year as VGA (1987) based on the 82C451, opening up the IBM compatible graphics display market.[11] This market was then entered by companies such as Trident Microsystems, Western Digital, Cirrus Logic, Oak Technology, and others, until it was saturated.
The 82C480/82C481 series is fully compatible with the IBM 8514/A graphics controller and accelerates 2D GUI operations on a 32-bit VRAM interface. [12]
Chips and Technologies provided the Wingine video card, a very high speed framebuffer that sat in a proprietary local bus slot on supported motherboards. Epson and JCIS were two manufacturers who offered motherboards featuring the Wingine local bus slot. The Wingine was popular with users of NEXTSTEP for Intel processors, as it was one of the highest performing video cards supported by the operating system.[13][14] Latest HiQVision architecture (65550, 65554, 65555, 68554, 69000 and 69030) was aimed at low-cost, high performance, highly integrated products with flatpanel/LCD direct drive features.
Apple used a number of C&T controllers in its PowerBook line. Among others, the 65550 was used in the PowerBook 3400[15] and the faster 65554 was used in the "Kanga" PowerBook G3, which was derived from the 3400.[16] Early NuBus PowerBooks such as the PowerBook 1400 used the less-sophisticated 65525A.[17]
C&T eventually ended up competing in the low end of the video market, the 65555 featured an LVDS transmitter and notably won a design in early Compaq Armada laptops.
