You may be thinking of the GDI, USER and SYSTEM resources.  I think in Win98
each of these is a 64K block of memory.  If any of them gets completely
used up, your computer may run extremely slowly or crash.  Different programs
use different amounts of the various resources - for instance a really long
and complicated web page can use them up completely; it's the only thing
I've seen do it.  Running a lot of programs concurrently will use up a lot
of system resources.

Having said all that I don't believe that the "resources" which were referred
to in the Technet note I referred to were connected with the system resources
I have described above, but I'd have to re-read the article in more detail.
 The main problem is the annoying habit of the Win9x file management system
grabbing all "spare" memory for file cache.

I've never had this problem with Win98SE, but then I don't use Eudora or
Info Select.  The only program I use which noticeably mucks up available
memory and/or resources is Vuescan.

As has been suggested elsewhere, you could give it a try. With RAM as cheap
as AUD$80 for 256MB why not? On the other hand I'm reasonably sure the main
bottleneck in my PC when dealing with large scans is the 5400RPM IDE drive.
 A 7200RPM drive would speed up loading and saving files by at least 25%.
 Two 7200rpm drives in a RAID array should be significantly better still.
 Loading and saving files is the no.1 timewaster for me when working with
film scans on my PC.
