Apple's memory offerings recently went through a slight change. Our current Macintosh memory upgrades are all 70ns.
Quadra 800, Quadra 840AV and Workgroup Server 80 customers requiring 60ns SIMMs should purchase SIMMs through 3rd party sources.
Apple currently offered 4MB, 8MB, and 16MB 72-pin SIMM upgrade kits.
M3651LL/A Macintosh 4MB Memory Exp. Kit (1-4MB SIMM)
M3652LL/A Macintosh 8MB Memory Exp. Kit (1-8MB SIMM)
M3372LL/A Macintosh 16MB Memory Exp. Kit (1-16MB SIMM)
These kits may be used in the following systems:
* LC III, 475, 520, 550, 575
* Performa 450, 460, 466, 467, 475, 476, 550
* Macintosh TV
* Centris 610, 650, 660AV
* Quadra 605, 610, 630 family, 650, 660AV
* Power Macintosh 6100, 7100, 8100
* Apple Workgroup Server 60
Note: The Quadra 800, 840AV, and Workgroup Server 80 require 60 nanosecond SIMMs and thus will not be supported by the new DRAM Upgrade Kits. Upgrade Kits for these systems can be purchased from a variety of 3rd party sources.
