			Have a M100 with only 8kB of RAM? If you open up the laptop,
			and Option RAM #1,2,3 are empty then this is for you.
			This single card provides 24kB to bring the system up to 32kB,
			replacing 3 "standard" M100 8kB RAM modules.
			It plugs right in!
			(NOTE: intended for PLX110CH1X or PLX110EH1X board revisions only)

	Tandy made 2 variants of M100 available - 8kB (26-3801) and 24kB (26-3802).		Tandy made 2 variants of M100 available - 8kB (26-3801) and 24kB (26-3802).

== Add 24kB to your 8kB M100! ==

Tandy made 2 variants of M100 available - 8kB (26-3801) and 24kB (26-3802).
This card provides an additional 24kB to the 26-3801, for a total of 32kB.

This add-on card plugs into the unused SRAM sockets Option RAM #1,2,3 - and provides
an additional 24kB in one go!

In this image you can see, as indicated by the red box, where the SRAM module should be placed.

== Installation ==

1. For M100, remove the 4 screws and separate top from bottom, so you can access the SRAM sockets.
2. Align and orient the SRAM card over the sockets.
For M100, you are installing 24kB in Option RAM 1,2,3.
3. Carefully press the SRAM card until it is fully seated in the sockets.
Be careful not to bend the pins!
4. Reassemble the computer, turn on and run a memory test to confirm the installation is good!
