Compatibility
=============
The 7-inch PC Compatibility cards uses JEDEC-standard 168-pin DIMMs (dual inline memory module) DRAM cards. The DIMMs should be 64-bit-wide, 168-pin fast-paged mode (FPM), 2K refresh rate with a 70ns RAM access time or faster. DIMMs built with either Extended Data-out (EDO) or asymetrical DRAMs are not supported on the 7-inch PC Compatibility card.
All DIMMs currently available from Apple Computer are 2K refresh rate so you can safely use them in your 7-inch PC Compatibility card.
Expansion
=========
The 7-inch PC Compatibility card has one RAM expansion slot on board. You can use DRAM configuration with DIMMs of these sizes: 8, 16, 32 or 64 MB. The exact configuration depends on the density of the DRAM chips that are mounted on the DIMMs. You can increase the 7-inch PC Compatibility cards total DRAM to up to a maximum of 64 MB.
