[1] The name of the company, as well as many of its products (e.g., Revolution, Imagine, Pepper, Ticket to Ride) refer to Beatles songs.

Number Nine initially made an Apple II accelerator board, then later moved into the design and manufacture of high-end PC graphics cards in 1983.

In the mid to late 1990s, Number Nine began to lose market share to competitors in both the price and performance arenas.

A volunteer and #9 enthusiast provided regular, impromptu technical support on the forum for the last two and a half years the site was active.

[citation needed] In 2013, Francis Bruno from Silicon Spectrum tried to fund an open-source GPU based on a #9 Ticket To Ride IV derived design.

In the latter 1980s to early 1990s, Number Nine made ISA and MCA bus graphics cards based on Texas Instruments' TIGA coprocessors.

The Texas Instruments TMS-340x0 co-processors were coupled with custom Number Nine-designed application specific chips, which could only handle very primitive graphics functions such as clipping.

[15] The Imagine 128-II added Gouraud shading, 32-bit Z-buffering, double display buffering, and a 256-bit video rendering engine.

[16] The Ticket to Ride (Imagine-3) supported WRAM and both the AGP and PCI buses, had a 3D floating point setup engine, bilinear filtering and perspective correction, Gouraud shading, alpha blending, interpolated fogging, specular lighting, double and triple display buffering, 16-, 24- and 32-bit Z-buffering, MPEG-1 and MPEG-2, and hardware MIP mapping.

[17][18] The Ticket to Ride IV included an integrated 250 MHz RAMDAC, support for up to 32 MiB SDRAM, full scene anti-aliasing, per pixel fog, specular, and alpha effects, 10-level detail per pixel MIP mapping, bilinear and trilinear filtering, 8 bits per texel, 8 KB on-chip texture cache, hardware MPEG-1 and MPEG-2, and a full IEEE 754 floating point pipeline 3D rendering setup engine.

For this reason, for a time, Revolution IV-FP and Oxygen VX1-1600SW video cards commanded a premium price in the used market, long after they were out of production.

On April 20, 1999, Bankboston Business Credit announced it had provided $15 Million for Number Nine Visual Technology.
