Yes, it does.

Decent? Errr... Duhhh... My hardware browser on the current (newest)
machine tells me hda1 has 102 MB, hda2 has 14002, and hda3 has 486. My
System Monitor shows Used Memory and Used Swap pretty steady at 104 of 115
MB (used to be 112 or 113 of 115), and 161 of 486, respectively.
It also lists my video card as an SiS 650, and (Geom: 1860/255/63) as well
as (Model: ST315320A) for hda -- none of which means squat to me, decent
or not.

How do I do that?

That did help -- bringing the 112 or 113 of 115 down to 104, and
increasing apparent speed discernibly. Thanks!

This machine being newest, I haven't tried that yet; the backup already
has all the tech at the computer store says will go in it.
