For Sale is a used IBM 8514 VGA Microchannel video adapter also called a PGC ( professional graphics controller ) or PGA ( professional graphics Adapter ).
I found this board wrapped in an anti-static bag in a box that has been in storage sense the late 1990's. It was marked as a good spare.
I have no way to check a microchannel card so... &n...bsp; Being sold AS-IS.
Additional information.......
IBM 8514 is an IBM graphics computer display standard supporting a display resolution of up to 1024x768 pixels with 256 colors at 43.5 Hz, or 640x480 at 60 Hz. 8514 usually refers to the display controller hardware However, IBM sold the companion CRT monitor which carries the same designation, 8514 Before the 8514/A, in 1984 IBM introduced a multi-board AIBs called the Professional Graphics Controller (PGC) often called Professional Graphics Adapter and sometimes Professional Graphics Array.The 8514/A was the first fixed-function graphics accelerator for PCs with the support of 1024×768 resolution and up to 256 colors. The basic 8514/A with 512KB VRAM only supported 16 colors; the 512KB memory expansion brought the total to 1MB VRAM and supported 256 colors.Along with the introduction of the 8514/A was a 16-inch 1024 × 768 CRT monitor. The 8514 is the monitor; 8514/A is the AIB with the “/A” designating adapter, not version (there is no 8514/B). 8514/A was only a PS/2 accessory, and IBM didn’t produce any ISA versions; however, several clone suppliers did. In 1990 it was replaced with XGA, which was like VGA and 8514/A rolled in one.The 8514/A was the beginning of large-scale integration graphics chips and compared to the graphics controller of the PGC (Figure 1) the 8514-controller chip (Figure 3) was huge.The 8514/A was capable of four new graphics modes not available in VGA. IBM named them the advanced function modes, and in addition to 640 ×480. The three other modes got up to 1024 x 768 pixels; however, somewhat ironically it did not support the conventional alphanumeric or graphics modes of the other video standards since it executed only in the advanced function modes. In a typical system VGA automatically took over when a standard mode was called for by an application or the OS.
