The 8514 initially sold for $1290 for the adapter and $270 for the 512 KB memory expansion (equivalent to $3500 and $720, respectively, in 2023).[3] The 8514/A required a Micro Channel architecture bus at a time when ISA systems were standard.
History
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[by whom?] 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.[citation needed]
Later compatible 8514 boards were based on the Texas Instruments TMS34010 chip.[citation needed]
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. [citation needed]

The 8514 was superseded by IBM
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.

Clones
In the late 1980s, several companies cloned the 8514/A often for the ISA bus. Notable among those was
- ATI Technologies: the Mach8, Mach32,[1] Graphics Vantage and 8514/Ultra

- Paradise Systems: Plus-A, Renaissance Rendition II
- Desktop Computing: AGA 1024 (also capable of emulating TIGA standards)[8]
- NEC: Multisync Graphics Engine
- IIT AGX and Tseng Labs ET4000 are also referenced as being IBM 8514 compatible.[5][9][10]
