[comp.sys.mac] adding two meg to macII

spud@metasoft.UUCP (David Hayes) (11/12/87)

my apologies to those of you who have seen (or given) answers to this
question before.

	What resistor needs to be cut (or other adjustment made)
	to the macII mother board after adding two 1 meg simms ?
	
	i tried the "pop 'em in and hope" method but to no avail.
	
	i thank you, and my macII thanks you.
	
	responses by e-mail appreciated. spud@metasoft.uucp

You don't need to cut a resistor to install SIMMs in a Mac II, only a Plus or
an SE. You cannot install just 2 SIMMs modules into the Mac II - you must
install 4. From that, you get the possible memory configurations below:
	1 MB		4 256K SIMMs
	2 MB		8 256K SIMMs
	5 MB		4 256K SIMMs & 4 1MB SIMMs
	8 MB		8 1MB SIMMs
You need to use SIMMs of 120 nanosecond (or less) access time. There is an
exact way in which the SIMMs must be installed for 5MB, but I don't have the 
information handy at the time.
