Four.

>How many are used in the shipped configuration?

Two or four.

The standard [original] SE is shipped with four 256K SIMMs in place, giving a
total of 1 megabyte of RAM.

The SE 2/40 is shipped with 2 1-meg SIMMs in place, giving a total of 2 
megabytes of RAM.

The SIMMs must be replaced in pairs, so the possible memory configurations in
an SE are:

	 256	 256	 ---	 ---		=	512K RAM
	 256	 256	 256	 256		=	1024K RAM
	1024	1024	 ---	 ---		=	2048K RAM
	1024	1024	 256	 256		=	2560K RAM
	1024	1024	1024	1024		=	4096K RAM

Which are, top to bottom, 1/2, 1, 2, 2.5, and 4 megabytes.

Does that over-answer your question?

You're welcome.
