interference, correct it by doing any of the following:

0Reorient the receiving antenna or plug.

0Change the relative positions for the peripheral and the receiver.

0Plug the equipment into adifferent outlet so that the peripheral

and receiver are on different circuits.

CAUTION:Onlyequipmentwith shield‐groundedcables (computer

input-outputdevices, terminals, printers,etc),certiﬁed to comply with

Class Blimits, can be attached to this device. Operation with non‑

certiﬁed equipment may result in communications interference.

Your house AC wall receptacle must be athree-pronged type (AC

ground). If not,contact an electrician to install the proper receptacle. If

amulti-connectorbox is used to connect the computer and peripherals

to AC,the ground must be common to all units.

If necessary, contact your dealer or an experienced radio‐TV

technician for additional suggestions. You may ﬁnd the following FCC

INTRODUCTION

The Great Valley Products (GVP) Impact Series II product line offers

awide range of high-performance add-on peripheral products for the

Commodore Amiga computer systems. This manual serves as the User's

Guide for the following products:

0ImpactSeries II A2000-HC+8. This product is GVP's ﬂagship SCSI

controller. This controller has room to mount, directly on the

card, a3.5" SCSI hard drive aswell asthe capability to hold up to

eight (8) megabytes of Fast RAM.

0Impact Series II AZOOO-HC. This product is similar to the A2000‑

HC+8 but does not contain the expansion RAM capability. This

controller has room for a3.5" SCSI hard drive to be mounted

directly on the card.

Akey feature of all GVP Series II SCSI/RAM controllers is the new

GVP DPRC. The DPRC isacustom Dual-Port RAMController chip that was

designed exclusively by GVP and is currently only available on GVP Series

IISCSI/RAM controller products.The DPRC allows GVP to achieve some of

the fastest SCSI transfer rates of any controller in the Amiga market.

INSTALLING ADDITIONAL FAST RAM IN

GVP’s IMPACT SERIES ll SCSI/RAM CONTROLLERS

Adding RAM to the board is relatively simple and requires only a

few steps.

The RAM that should be used is lOOns (nanosecond) or faster, page

mode DRAM SIMMs. DRAM stands for Dynamic Random Access Memory

while SIMM stands for Single Inline Memory Module SIMMs are used

because oftheease of installationaswell asthe space they save. GVP uses

1Mx8 SlMMs. This means that there are 8individual DRAMchips soldered

to asmall circuit board These SIMMS can come in two different styles,

both styles are shown below:

Step 1:

The SlMMs must be inserted in aspeciﬁc order. They go in from

the innermost (CNlO) to the outermost (CN17) sockets (see diagram

at beginning of Chapter 5). The maximum conﬁguration is eight mega‑

bytes and in this conﬁguration all the SIMM sockets will be ﬁlled. With

two megabytes only the ﬁrst two sockets (i.e. CN10and CN11)will be ﬁlled

and with four megabytes the ﬁrst four sockets will be ﬁlled.

The SlMMs can only beinserted in one direction since they are keyed.

This key prevents the SlMMs from being inserted backwards and being

damaged. Once the SIMM is in its socket, apply slight pressure to the top

of the SIMM to ensure that it is properly seated. When the SIMM is being

seated, it will generally snap intoplace. SlMMs must be inserted in incre‑

ments of two (i.e. 2, 4, 6. 8).

Step 2:

Nowyou mustset the proper jumpers so that the system knows about

this new expansion memory. There are ﬁve jumpers on the board below

the word “TRAM The diagram at the beginning of Chapter 5indicates

where the jumpers are located. The chart below indicates the proper

jumper settings:

Memory SIMM Locations 15 16 I7 18 I9

0NONE

2CNlO-CNll ON

4CNlO-CN13 ON

6CNlO-CNIS OFF

8CNlO‐CNl7

Once the proper jumper settings have been made, you should

proceed to Chapter 5on how to install your ImpactSeries 1]board in your

Amiga 2000.

INSTALLING THE FIRST HARD DRIVE ON A

GVP SERIES II SCSI/RAM CONTROLLER

If you purchased your GVP Series II controller with no hard drive

attached and wish to attach ahard drive, just follow these few steps:

Step I:

First it is necessary to physically prepare your hard drive. The follow‑

ing items must be taken care of:

0The SCSI ID number should be set to zero

0The terminating resistor packs should be removed

(see Chapter 4)

In order to set the SCSI ID to zero, you should read the manual that

came with the hard drive. Usually, aSCSI ID of zero means that all SCSI

ID jumpers are removed,but refertothe owner's guide that comeswith the

drive. The same applies to the resistor packs. It is necessary to refer to the

owner's guide of the hard drive in order to ﬁnd out how to remove the

resistor packs.

Once the SCSI ID is set and the resistor packs have been removed,

proceed to the next step.

Step 2:

Since the drive has to be mounted on the card and connected to two

cables, it is best to connect the cables ﬁrst. Beginby connecting a50-pin

ribbon cable to the controller at the location speciﬁed in the ﬁgure shown

in the beginning of Chapter 5. The ribbon cable is keyed and so is the

connector on the GVP board, so it can only be inserted in one direction.

After the ribbon cable is attached to the controller, it is necessary to

attach the other end of the ribbon cable to the hard drive. The hard drive

has the same connector as the GVP board, so attach the other end of the

ribbon cable to the hard drive keeping in mind the key. Next,you should

connect the 4-pin power connector to the hard drive. This connector is

located on either side of the SCSI connector. Included with your GVP

Board was asmall four-wire cable with aconnector on either end. The

small end plugs intothe connector on the board and the large end plugs

intothe harddrive. This connector isalso keyedat the corners and can only

be inserted in one direction.

Once the two cables are connected, you can use the four screws that

came with the GVP controller to secure the hard drive down to the board.

if you are using the new one-inch high Quantum drives, only three

screws are required. The location for the forth screw is not drilled on

the drive, this is left blank intentionally.

Now reinstall the GVP Series [1controller as per Chapter 5.

INSTALLING ADDITIONAL HARD DRIVES ON THE

GVP IMPACT SERIES II SCSVRAM CONTROLLER

Up to seven SCSI peripheral devices can be attached to any GVP

Impact Series II controller. These devices may be hard disk drives,

tape drives, CD-ROMs, etc. There are afew concepts to understand

about the SCSI interface that should be explained before you do the

actual installation.

SCSI ID:

Each SCSI peripheral must have itsown SCSI ID. SCSI IDs range from

zero to seven. However, the Impact Series II controller itself uses SCSI ID

number seven. Therefore no other SCSI peripheral may use aSCSI ID =7.

Terminating the SCSIBus:

Since SCSI devices are chained one after another in a"daisy chain",

the last device needs some special attentionThe end oftheSCSI bus must

be terminated with terminating resistors. Terminating resistor packs are

small plastic packages, usually with eight pins coming out of them. The

ﬁgure below shows atypical resistor pack:

Note: Some SCSI peripherals do not have terminating pachs, instead they have

terminating plugs/connectors which serve the same purpose. Please refer to the appropri‑

ate user’s guide for more information.

Only the last SCSI device in the chain should contain the resistor

packs. It is essential that the terminating resistor packs are removed from

all but the last SCSI device. If there are both internal and external SCSI

devices, then the last external SCSI device is considered to be the last

device, therefore usingthe terminating resistor packs. This means that all
