XLR8 is now shipping multiprocessor upgrades for six slot legacy Macs. The Carrier ZIF SSE is designed to make older six slot Mac compatible with G4 processors. Three editions are available including a 450 MHz MACh Carrier and an unpopulated board compatible with XLR8 ZIF G3 and G4 processors. According to XLR8:
Today XLR8, the leading manufacturer of multiprocessor upgrades and expansion products, announces the latest version of the award winning Carrier ZIF, the Carrier ZIF SSE (Six-Slot Edition).
Available in three configurations - the 400 MHz MACh Carrier G4 SSE, the 450 MHz MACh Carrier G4 SSE and an unpopulated board compatible with Apple and XLR8 ZIF G3 and G4 processors, the Carrier ZIF SSE.
These products bring Motorola G4 compatibility to Macintosh clones with PCI cards in more than 3 of their six slots as well as the popular 9500 and 9600 series of six slot Apple Macintosh computers.
These flexible processor upgrade cards are the solution to power users who have been unable to utilize the powerful Motorola G4 processors in their computers due to an inherent hardware incompatibility.
