INTRODUCTION
Congratulations on buying this advanced specification AMITEK Hawk, Amiga 1200
expansion board. While the Amiga 1200 is one of the most popular and technically
impressive microcomputers on the market, it can be expanded via its wide range of
peripheral, card and board connections. Once installed in the A1200’s trapdoor, the
AMITEK 1200 board provides:
RAM EXPANSION
The AMITEK Hawk supports 1Mb, 2Mb, 4Mb or 8Mb of 32-bit FAST RAM which not only
enables you to run larger and more complicated software packages, but also
dramatically speeds up read and write operations to your machine’s memory. The Hawk
also runs with Zero Wait States enabling your A1200 to perform at its maximum speed.
OPTIONAL FLOATING
POINT UNIT (FPU)
In addition, the Hawk board allows the
installation of a Floating Point Unit
(FPU), also known as a maths co-
processor, to dramatically increase the
speed of mathematical calculations.
This will be noticeable in most
applications such as rendering of 24-
bit, animated and vector graphics, plus
number crunching in professional
applications.Ifyourboardwasnot supplied
with an FPU, don’t worry, the AMITEK
Hawk includes a plug-in PLCC connector for easy installation. Most good dealers
should hold FPU’s in stock. Full fitting instructions are available on pages 9 and 10.
BATTERY BACKED-UP CLOCK
The battery backed-up clock ensures that the date and time you have set up on your
Amiga 1200 is constantly updated even when the main power supply is turned off.
Such a facility is important, for example, when endeavouring to discover the most
current version of a date stamped file.
Once installed, the AMITEK Hawk expansion board will ensure that your Amiga has a
long and technologically advanced life and, the ability to run the latest, most complex
software titles at a speed way in advance of the standard A1200. It’s operation is also
almost invisible. All you need to know is that you now own one of the most advanced
combo expansion boards on the market.

INSTALLING THE AMITEK HAWK IN YOUR AMIGA 1200
The following easy to understand installation procedure will have your Amiga 1200
and Hawk board up and running within minutes:
1. Disconnect your Amiga from the power source and monitor/TV. Also,
unplug any peripherals inc. joysticks, floppy drives, printers or modems.
2. Carefully turn your Amiga upside down, resting it gently on a firm surface
so as not to damage the keyboard.
3. Remove the panel which covers the trapdoor expansion slot. It can be
simply removed by inserting the edge of a flat bladed screwdriver, coin, or
blunted knife into the indentation, and prying off the cover (see fig. 1.1).
Beneath it you will find the open access to your Amiga’s main circuit board
and, most importantly, the expansion connector which can be fitted with a
wide variety of external devices including your Hawk Expansion Board.
4. WARNING: Chips on the AMITEK board are very fragile and could fall prey
to the small currents of static electricity generated by your body. Before you
begin to install the board we suggest that you:
(a) AVOID standing on a carpeted area, rubber soled shoes can be used
as an added precaution.
(b) ALWAYS touch a grounded metal surface before handling the board
i.e. radiator panelling. This will ensure that any static charge is dis-
charged when you start work.
(c) If available, WEAR a grounded wrist strap.

5. Remove the board from its protective anti-static packaging and, with SIMM
socket (see fig. 2.1 on page 7) facing toward the back panel of the computer,
gently ease it onto the gold edge connector in the expansion slot (see fig.
1.2). Take great care that the memory expansion board is flush with the
connector and not at an angle. Press the board in firmly so as to create a
good connection (see fig. 1.3) and replace the plastic trapdoor panel.
6. Turn your computer over and replace all cable connections and peripherals.
7. Connect yourAmiga to the power source.
8. Insert the Workbench disk into the floppy disk drive.
9. Power up. If the power light does not come on, or the A1200 does not start
up correctly, turn the power off immediately and re-check your connections.
To check your memory, load Workbench. You should notice on the top line of the
display that you now have some “OTHER MEMORY”. This amount should show
approximately as follows:
RAM on Board “OTHER MEMORY” (approx)
1Mb Fitted 1,050,000
2Mb Fitted 3,100,000
4Mb Fitted 4,200,000
8Mb Fitted 8,400,000
IMPORTANT:
Do not power-up the Amiga 1200 without replacing the
trapdoor as it holds your expansion board in position.

ADDING RAM TO THE BOARD
SIMM memory chips are designed to be easily installed and allow the flexible
configuration of an Amiga 1200’s RAM capacity. Each chip has a fixed capacity
measured in Megabytes (Mbs). The higher the number of Megabytes, the greater the
amount of storage available to your Amiga.
The AMITEK expansion board has one SIMM socket (see fig. 2.1), that can be
populated with 1Mb, 2Mb, 4Mb or 8Mb SIMMs. The FAST RAM used is of the 72-pin
SIMM type and is the same as the RAM available in the high specification Amiga
4000. The AMITEK board will accept RAM that is 80ns (nanoseconds) in speed, or
quicker (the lower the nanosecond rating, the faster the RAM performs). This SIMM is
either supplied as part of the product that you have purchased or can be bought from
your local Amiga dealer.
Fitting SIMM boards is an easy operation which should take only a few seconds. It
can either be done before the board is installed in your Amiga or when you decide to
upgrade your machine’s memory and the board is already in place. In the latter case,
you will need to remove the AMITEK board from the Amiga’s trapdoor slot making
sure power is switched off before removing.
If you are in any doubt about fitting the SIMM boards, contact your dealer who should
be able to help.
NOTE 1 - The 72-pin SIMM was designed to allow the user to fit it into a SIMM socket
only ONE way. It is not possible to install a SIMM the wrong way round.
NOTE 2 - The AMITEK Expansion will not allow the use of slower PCMCIA memory
cards. If you have previously used a PCMCIA RAM card, you will notice a significant
speed increase in your Amiga when you use this AMITEK product.

INSTALLING SIMMS
We suggest that you gain a firm understanding of the following instructions before
you proceed with installation.
1. Lay the expansion board on anti-static material, such as its original board
packaging, with the SIMM socket exposed.
2. Position the SIMM with the keying notch to the left (see fig. 2.1 on page 7).
Hold the SIMM at both ends and insert its metal contacts into the metal
jaws of the SIMM socket. The 72-pin SIMM was designed to allow the user
to fit it into a SIMM socket only ONE way.
3. When all the pins are flush and securely in the jaws of the socket, apply
enough pressure on the top of the chip to push the SIMM into the socket.
Maintain this pressure until the tension springs at the side of the socket lock
the SIMM into place (see fig. 2.1). Equal pressure should be maintained to
both side of the chip, as damage could be caused to the SIMM or SIMM
socket.
4. You now need to change the jumper settings on the component side of the
board to match that of the RAM now installed (see fig. 2.2). Failure to do so
will result in board malfunction. Possible jumper combinations are shown in
the table below (see fig. 2.3). The three jumpers are clearly labelled LK1,
LK2 and LK3 on the board. If you have 1Mb on board follow the settings in
the first row, 2Mb on board follow the second row, etc.
REMOVING SIMMS
Push both tension springs (see fig. 2.1 on page 7) outwards at the same time and the
SIMM should come forward ready to be lifted out.

ADDING AN FPU TO THE BOARD
The AMITEK A1200 Expansion board can also accommodate an FPU (Floating Point
Unit) to increase performance of maths calculations. This type of co-processor works
in parallel with the main central processing unit, taking over much of its arithmetic
work with real (i.e. floating point) numbers. It can be particularly important if you
intend to do a great deal of number crunching work with spreadsheets, complex
equations or calculus. As your Amiga handles all low level operations in terms of
mathematics, an FPU can even speed up tasks such as simple animation and
complex 3D image generation where the activity of the maths co-processor makes a
critical difference in the calculation of graphics formulae.
Your new AMITEK RAM expansion board has a PLCC 68881/2 (rather than PGA)
type of FPU socket.
The large range of FPU’s run at different rates which are measured in MHZ: the higher
the number, the faster the speed. An FPU may also come with a crystal oscillator that
can regulate the operation of the FPU. If, however, you do not have a crystal, you
must run the FPU at the same time speed as the machine (14.3MHZ).
There are various types of processor which you can install on the AMITEK board, all
of which are distinguished by their individual processing speeds. The available chips
run at 16MHZ, 20MHZ, 25MHZ, 33MHZand 40MHZ- the latter of which is the top of the
range for most RAM combo boards. You may find one is supplied as part of the
product that you have purchased, or you can buy one from your local Amiga dealer.

INSTALLING AN FPU
To install an FPU on the AMITEK board, please follow the instructions below:
1. The FPU is square and should be marked with a positioning mark (usually a
dot) along one of its four edges. This edge must be aligned with the edge
that the arrow is pointing to inside the FPU socket on the board (see fig. 3.1
on page 9). Simply place the FPU squarely onto the socket and push down
evenly until the chip falls into the socket.
2. The AMITEK board also contains a socket for a crystal which regulates/
controls the overall speed of the FPU when it is installed. It is smaller than
the FPU and silver in colour. Examine the crystal and locate the notch or
dot at one end. This end needs to match the socket end, with the half circle
cut-out facing the jumper (see fig. 3.1 on page 9). Line up the markings and
push the chip firmly into place.
3. Set the jumper LK4 to either INT to use the machine’s clock of 14.3MHZ, or
to CPU to use the speed of the crystal that you have fitted.
IMPORTANT:
Before installing the expansion board into your computer, it is important to ensure that
the crystal is not faster than the FPU fitted. Any mistakes could result in the over-
clocking of the FPU and damage to the chip which will void your warranty.
REMOVING/UPGRADINGAN FPU
You may upgrade the installed PLCC - e.g. from 25MHZto 40MHZ- by taking the old
chip out of its socket and installing the new chip using the above outlined procedure.
To remove the old chip without damaging the socket or fragile legs on the FPU, it is
recommended that you use a dedicated FPU puller, similar to tweezers, which can be
obtained from your local dealer or electronics supply shop. Alternatively, good Amiga
dealers can perform this upgrade.
