2 MEG Plus  
Memory Expander  
This guide tells you how to install and configure your  
RamWorks 2 MEG PLUS Memory Expander card. The  
-
RamWorks 2 MEG PLUS Memory Expander is an  
accessory printed circuit card for both the RamWorks II  
and RamWorks III extended memory cards. (The 2 MEG  
PLUS will not work with the original RamWorks card. The  
original RamWorks had only two rows of RAM chips with  
a maximum capacity of 512K.)  
When installed on either RamWorks II or III, it will  
provide an additional 1 to 2 megabytes of RAM (Random  
Access Memory) storage. Unless specifically noted, the  
name "RamWorks" in these instructions refers to both the  
RamWorks II and the RamWorks III cards.

V. 1.1  
Installing the 2 MEG+  
- - First, TURN OFF THE POWER SUPPLY.  
- - Remove the cover from your IIe.  
- - Discharge any static electricity on your body by  
touching the IIe power supply case before touching  
any of the components.  
*
Warning! Don’t ZAP your chips! There are many  
static sensitive components in the IIe and on the  
RamWorks and 2 MEG+ Memory Expander cards. Be  
sure that you touch the power supply case before  
continuing.  
- - Remove the RamWorks card.  
- - Carefully line up the pins on the underside of the 2  
MEG+ Expander with the corresponding sockets on  
the chip side of the RamWorks card. Refer to the  
illustration below.  
-- Press the pins gently but firmly into the sockets until  
they are fully seated. (Even when it's fully seated  
there may still be some of the pin showing between  
the connectors, so don’t press too hard!)

Now, re-install the expanded RamWorks following  
the installation instructions in your user’s manual  
Te s t i ng Your 2 MEG+  
After installing the Expander card, you should test it by  
running the RamWorks Memory Test on the AppleWorks 2  
Expander disk (Version 1.3) or the Super AppleWorks  
Desktop Expander disk. The test will display X’s on empty  
sockets and bad chips. Those sockets containing good chips  
will be displayed as clear rectangles.  
Adding Even More Memory...  
There are sixteen RAM chip sockets on the 2 MEG+ Expander  
which can accommodate from 1 to 2 megabytes of RAM, using  
groups of eight 1 megabit dynamic RAM chips.  
Memory chips with the correct specifications can be obtained  
at some computer or electronics parts stores, or you can get  
them through Applied Engineering; possibly at a lower cost.  
Because Applied Engineering gets bulk-quantity discounts on  
its purchases of memory chips, we can often offer them at  
lower prices. We use high-quality memory chips and warrant  
them for 5 years. (Most electronics parts vendors sell their  
chips ‘as is.”) With Æ memory chips you are also assured of  
getting the right chips.  
Memory Chip Installation  
Memory on the 2 MEG+ Expander is organized into two  
BLOCKS, shown as A and B in the illustration below. Each  
block must be completely empty or completely populated with  
8 D-RAM chips. It is recommended that you fill block A first,  
then block B. (See graphic following.)

It is extremely important to insert the Expander’s memory  
chips properly. The illustration shows the correct  
orientation of the RAM chips and which memory chip  
sockets are allocated to each block on the 2 Meg+  
Expander. Note the position of the notch (or dot on some  
chips). Each RAM chip should have all legs fully seated in  
the socket and in the correct position.  
OOPS! If power is applied to a chip that is plugged in  
backwards, the chip will probably be zapped  
immediately. The chip will be damaged. However, no  
harm should be done to the board.  
Note: You may return your RamWorks card and/or  
RamWorks Memory Expander to Applied Engineering  
for a memory upgrade with no additional charge for  
the installation or testing. Call Applied Engineering  
Sales for the latest memory chip prices. The sales  
office phone number is (214) 241-6060.  
Bank Configuration for Programmers  
The table below shows the relationship between the chips and  
the bank numbers. From this table you can determine the  
addressable banks for each of the chips. The bank designations  
are in hexidecimal notations.

Problems?  
If you require more information on using the expanded  
memory, please see your RamWorks II or RamWorks III  
Users Manual. If you encounter any difficulties in the  
installation or use of the card, contact the dealer from whom  
you purchased the card. Most dealers are knowledgeable about  
the products they sell and will be able to help you. In the event  
that the dealer is not able to solve the problem, contact an  
Applied Engineering Technical Support representative.  
Applied Engineering’s Technical Support representatives are  
technicians dedicated to helping you by answering your  
specific questions about Applied Engineering products.  
* Note: You MUST have a Return Material  
Authorization Number (RMA) for any items sent for  
service to Applied Engineering Technical Support.  
Not having an RMA will cause delays and create  
additional expense.
