Hm, interesting...back when my LCII was a current Mac, a number of people
asked support forums like this & assorted other Mac sages of the ages
whether putting 80ns or faster SIMMs in place of the 100ns spec'd would make
these slowpokes run faster. The answer, uniformly was no, because the memory
controller was permanently set to 100ns. Your reply, tho', makes me wonder
whether that was just true of Macs with some soldered-in RAM (as nearly all
current models were in those days), as the soldered RAM had to hold back the
potential of the faster RAM for the sake of coherent bus traffic?
I wonder if that doesn't apply to models (like, for instance, 2 that I own,
the IIfx & the 7200) that only have SIMM slots? "They" say that when
upgrading the processor on (say) the 601-604e PCI machines, it often works
better if the RAM is all bumped up to 60ns. Would it be true of the all-slot
IIs, do you think?
