Yes indeed, the SIMMS for the LaserWriter are NOT the same as the SIMMS for
regular Mac memory.  Why?  I don't have the faintest idea.  Apple does
sell, however, 1 and 4MB expansion kits for the NTX.  The NTX has 3 banks
of SIMMS, 4 SIMMS per bank.  Each bank can be populated with 256K (aka
1MB Expansion Kit)  or 1MB( aka 4MB Expansion Kit) SIMMS.
That means the possible configurations are:

        Total   Kits Used 
	-----   -----------
	1MB     (1MB, 0, 0)
	2MB     (1MB, 1MB, 0)     {Standard Configuration} 
	3MB     (1MB, 1MB, 1MB) 
	6MB     (4MB, 1MB, 1MB)
	9MB	(4MB, 4MB, 1MB)
	12MB	(4MB, 4MB, 4MB)

Hope that helps.
