Avance Logic 2201 VGA

The Avance Logic ALG2201 is a vintage VGA (Video Graphics Array) graphics card chipset developed by Avance Logic, a company that was active in the 1990s. VGA chipsets like the ALG2201 were commonly used in older personal computers to provide video output capabilities for monitors.

Key features and characteristics of the Avance Logic ALG2201 VGA chipset might include:

1. **Resolution Support**: The chipset likely supported standard VGA resolutions, including 640×480 and 800×600 pixels, which were common during the VGA era.

2. **Color Depth**: The chipset might have supported 256 colors (8-bit color depth) or 16 colors (4-bit color depth) depending on the mode and display capabilities.

3. **DAC (Digital-to-Analog Converter)**: The chipset would have included a DAC to convert digital video signals into analog signals required by CRT monitors of that time.

4. **Text and Graphics Modes**: The ALG2201 would have supported various text and graphics modes that allowed computers to display both textual information and graphical content on monitors.

5. **Memory Interface**: The chipset would have interfaced with video memory, which stored the display data. The amount of video memory could vary depending on the specific graphics card design.

6. **Compatibility**: The ALG2201 would have been compatible with the VGA standard, ensuring that it worked with monitors and software that supported VGA.

7. **Connectivity**: VGA graphics cards typically had VGA output ports to connect to monitors with VGA input.

8. **Driver Software**: The graphics card would have required driver software to properly configure and utilize its features on the computer’s operating system.

It’s important to note that the Avance Logic ALG2201 is a product from the early era of personal computing and is no longer relevant for modern systems. If you’re looking for historical information or if you’re working with vintage computers, the ALG2201 might be of interest. However, for contemporary computer usage, modern graphics cards provide significantly higher resolutions, color depths, and advanced features.
