Put the pedal to the metal with one of these easy-to-install accelerator cards
Caroline D. Hanlon
An accelerator card replaces the 8088 or 80286 chip in your PC with a faster 286 or 386. With one of these cards, you get many of the benefits of upgrading without the cost of a new system.
An accelerator card is generally easier to install than a motherboard, and doing so usually doesn't affect your computer's warranty.

How to Read the Chart
Speed refers to the maximum processing speed you can expect after installing the accelerator card. Add-ons refers to whether you can add another card to the accelerator card. Size of slots and installation requirements are given to help you determine if the card will work with your machine. Restrictions let you know what the card requires to work properly. Prices are for unpopulated (without memory) cards. Most companies offer technical support, and that's a good place to check if you have any questions about a card before, as well as after, you buy.
