RamWorks
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.
