The « Avarice » card from Apple

On eBay, sometimes you come across peculiar prototypes (it’s one of those days), like this « Avarice » card. If anyone has an idea of what it is…

The card is labeled « Avarice Proto » and is an EVT prototype, indicating it is from the early stages of development. It apparently incorporates two IBM PowerPCs, likely PowerPC 601+ based on the markings and the card’s production date (1994).
