IBM 8514

The 8514 was introduced with the IBM PS/2 computers in April 1987. It was an optional upgrade to the Micro Channel architecture based PS/2's Video Graphics Array (VGA), and was delivered within three months of PS/2's introduction.

Although not the first PC video card to support hardware acceleration, IBM's 8514 is often credited as the first PC mass-market fixed-function accelerator. Up until the 8514's introduction, PC graphics acceleration was relegated to expensive workstation-class, graphics coprocessor boards. Coprocessor boards (such as the TARGA Truevision series) were designed around special CPU or digital signal processor chips which were programmable. Fixed-function accelerators, such as the 8514, sacrificed programmability for better cost/performance ratio.

Later compatible 8514 boards were based on the Texas Instruments TMS34010 chip.

Even though the 8514 was not a best-seller, it created a market for fixed-function PC graphics accelerators which grew exponentially in the early 1990s.

The ATI Mach 8 and Mach 32 chips were popular clones, and several companies (notably S3) designed graphics accelerator chips which were not register compatible but were conceptually very similar to the 8514/A.[3]

The 8514 was superseded by IBM XGA.

The VESA Group introduced a common standardized way to access features like hardware cursors, Bit Block transfers (Bit Blt), off screen sprites, hardware panning, drawing and other functions with VBE/accelerator functions (VBE/AF) in August 1996.

Software that supported this graphic standard:[4]

• OS/2
• Windows 2.1
• Windows 3.x
• Windows 95[5]
• XFree86 2.1.1
• AutoCAD 10
• QuikMenu[6]
• Any BGI software using IBM8514.BGI

The 8514 offered:

• 640 × 480 graphics with 256 colors out of 262,144 (18 bit RGB); text mode with 80×34 characters;
• 1024 × 768 graphics with 256 colors out of 262,144 (18 bit RGB); text mode with 85×38 or 146×51 characters;

Latter clone board offered additional resolutions:

• 800 × 600 with 16-bit and 24-bit color depths
• 1280 × 1024 with 16-bit and 24-bit color depths

In the late 1980s, several companies cloned the 8514/A often for the ISA bus. Notable among those was Western Digital Imaging's PWGA-1 (also known as the WD9500 chip set), the Chips & Technologies 82C480, and ATI's Mach8 and later Mach32 chips. In one way or another, the clones were all better than the original with more speed, enhanced drawing functionality and overall improved video mode selections. Clone support for non-interlaced modes at resolutions like 800×600 and 1280×1024 was typical, and all clones had longer command queues for increased performance.
