Susan, the TigerDirect memory will probably work fine. They have a good
return policy; just be sure you understand its details before proceeding.
The quoted price, after rebate, is very competitive right now. Just four
months ago, I paid $45 each for two similar modules, and thought I was
getting a good deal then!

The "pin number" refers to the number of "fingers", the gold-plated contacts
along the edge inserted into the module slot.
The "parity" refers to whether it is ECC or non-ECC memory, i.e., error
correcting or not. Most consumer memory today is non-ECC, i.e.,
"non-parity".

Perhaps the biggest unanswered question at this time is whether your m/b
chipset supports 128-bit, or 256-bit memory modules. If you install only
the one 256 MB module and only 128 MB is recognized by the BIOS, then your
chipset cannot see all of the 256-bit memory, but detects only half of each
memory chip. You would need to install PC100 memory modules to use all the
available memory.

Hopefully, the purported Dell specs, indicating PC133 memory, is, in fact,
correct, and the suggested module will work perfectly. Be sure to seat the
module, gently, but firmly, until the retainers click. Watch the POST
screen closely to confirm that the BIOS detects the memory, and then observe
Control Panel / System, near the bottom of the page, to confirm that Windows
also detects all of it.

I found a place to order from but I am not sure about understanding specs
about memory.
US-Modular has
Memory Size 256MB
Memory Speed 133MHz PC133
Memory Type SDRAM
Pins 168
$24.99 with rebate from TigerDirect

Dell specs indicate computer needs following:
256MB SDRAM, PC133, Non-Parity, Unbuffered
Dell Part #: 842447-1, Manufacturer Part #: D48WJW
Dell wants $79.99 and that is quite a difference!

I don't understand the pin number and the parity. Are these related and
from
this can one tell if these memory cards are the same thing?

Thanks for information.
Susan

Jerry had this to say:

My reply is at the bottom of your sent message:

Go here http://www.windrivers.com/ and scroll down the homepage. You
will find a list of memory prices and a link to pages where they can
be bought.

As an additional resource you can see:

PC133 256MB :
http://www.pricewatch.com/prc.aspx?i=33&a=1948

Prices start at 20 dollars and there's a rating system there that will
give you a general idea of the business practices of that company and
the
satisfaction level of their customers. Prices listed will also include
shipping so you get the entire price. In all things check the return
policy as RAM has a history (not so common any more) of being DOA. After
installing the new RAM you'd want to run a memory diagnostics test
outside
of the OS with any one of the freely available testers that are online.
Failures should be returned with a listing of what the errors were.
