There shouldn't be any problem. How hard is it to slow
down?

They slow themselves down these days - when you don't need the power.

Isn't that why PCs used to have a Turbo switch - so you
could slow it down for things that couldn't keep up?

I think turbo switches were actually marketing ploys. I've never seen
anybody not run a machine with a turbo switch without it on, except by
mistake.


PC-100 SIMMs are getting hard to find and newer ones won't work in a
motherboard that's
designed for slower memory.

That's mostly a size thing.

It apparently loses its
memory before the next clock cycle. And suppose they come
up with a different connector like Firewire 800? Lots of
Firewire 400 stuff won't work on a Firewire 800 chipset
even if you make the plugs and jacks fit.

It looks like FW is slowly drifting away. I hear that even Apple is leaving
it off of some of their PCs. Given that you can get 4 FW ports on a $20
card, its not the costs that is forcing Apple to leave them off.

So, yeah, just how hard is it to slow down?

It happens all the time on modern PCs.

One other remark about flash RAM... We were talking
about archival use, where the card "just sits there",
without being rewritten.

True, but there's probably more than one failure mode,
and probably some that they haven't discovered yet. After
all, nobody anticipated sticky shed syndrome, though
fortunately there's something you can do to recover audio
from sticky tape.

The PC business' versions of that have been the recent boondoggles with
bursting caps and smoldering batteries.
