Abstract: An apparatus and method to accomodate a card designed to operate, with an alternate bus standard within a computer designed to operate with a primary bus standard, where the primary bus standard and the alternate bus standard are not directly compatible. The card is designed to fit within the computer in the available physical space and to connect to a card connector as required for the primary bus. However, the card is designed to be electrically compatible with the alternate bus standard. In a preferred embodiment the card draws power and any other signals, perhaps including clock, that are useful to both bus standards, but the address, data and control bus signals for the alternate bus are delivered to the card through an independent channel. This independent channel can be a separate connector to carry any signals needed for the alternate bus standard, which according to the application may or may not repeat signals already available through the primary bus.
