Ouch! I had forgotten about the EDO DIMM need. It has been several years
since I upgraded my other 6500. However, I was under the impression
(mistaken?) that you could use FPM in place of EDO if you sacrificed the
faster data flow of EDO. From an Apple document:
This update contains information you need to know if you
decide to add random access memory (RAM) to your computer.
It replaces information about dynamic RAM (DRAM)
specifications in the user�s manual and in the Technical
Information booklet for your computer. If you don�t need
the information immediately, save it with your user�s
manual so that you�ll have it if you ever decide to install
additional DRAM in your computer. Your computer has
Extended Data Output (EDO) DRAM Dual Inline Memory Modules
(DIMMs), not the fast-paged�mode DIMMs referred to in the
user�s manual and in the Technical Information booklet for
your computer. To take advantage of the faster RAM access
time of the EDO DRAM DIMMs already in your computer,
DIMMs installed later should be 64-bit wide, 168-pin
5-volt (V) buffered EDO DRAM DIMMs, with 60-nanosecond (ns)
RAM access time or faster, and a 1K or 2K refresh count.
Fast-paged�mode will be the default speed, if
fast-paged�mode DIMMs are mixed with EDO DIMMS.
Fast-paged�mode DIMMs slower than 60 nanosecond are not
recommended. The Single Inline Memory Modules (SIMMs)
from older Macintosh computers are not compatible with
your computer and should not be used. DIMMs that require
a 4K refresh count should not be used, either.
I had hoped to swap out the logic board using the RAM and G3 card from
the 6360 to get better performance. Didn't want to spend $$ on more RAM.
I upgraded the 6360 and the 6500 (my first) at the same time and I did
get two FPM DIMMS and two EDO DIMMS at that time. They weren't cheap then
aren't much better now.
