The ATI EGA Wonder 800 was an ISA-based EGA graphics card developed by ATI Technologies. Resolution capacities reaching 800x600 pixels, it facilitated a palette of up to 16 colors simultaneously from a palette of 64 colors. Operating within the Industry Standard Architecture (ISA) interface, the video signal is EGA RrGrBb TTL (Transistor-Transistor Logic) which refers to the signaling standard used in the Enhanced Graphics Adapter (EGA) interface a technology introduced by IBM in 1984.

Notes:
- OFF = OPEN, ON = CLOSED
- Switches 5 and 6 on a PC or XT motherboard must be set to ON.
- "MultiSync" monitors at this time tended to support 15-31.5kHz (NOT 31.5 and up), and used a 9-pin digital connector.
- 25kHz monitor requires Jumper P8 set to connect pins 2 & 3 (not available on VIP).
- Compaq Internal Monitor requires an "optional module" (no longer available).
- IBM Analog monitor support is only available on the VIP
