Introduction
Congratulations on adding the power of SCSI to your EPS or EPS-16 PLUS. We're sure that once you have experienced the speed with
which you can load sounds from a SCSI hard disk, you'll wonder how you ever did without it. Please read this manual carefully in order to
get the most out of your new SCSI
interface.
Except where noted, all descriptions in this manual apply equally to an EPS or EPS-16 PLUS equipped with a SCSI interface. The EPS-16
PLUS does have a few SCSI-related features not in the original EPS, and these are marked in the text "EPS-16 PLUS only." Otherwise,
wherever the text says "EPS-16 PLUS," BPS owners can substitute "EPS."
What is SCSI?
The great power and flexibility of the EPS-16 PLUS lies in the fact that it is really
a computer disguised as a musical instrument. The Small Computer Systems Interface (SCSI, pronounced "scuzzy") is a standardized
communication protocol for small computers (such as the Macintosh and the EPS-16 PLUS) and peripheral devices (hard disk drives,
CD ROM players, etc.) which allows for quick and efficient transfer of digital information. You may have up to eight SCSI
devices connected on a single SCSI network. These devices can be computers, disk drives, tape backup systems, musical instruments, and
other types of equipment.
Lick Set-up Guide
Here is an overview of what you must do to make your SCSI system work:
1. Obtain a SCSI hard disk on which the Priority/ID number can be set by an external switch (see p. 5).
2. Make sure that the SCSI cable has a Macintosh-type connector (DB-25P) on one end (see below).
3. Make sure your drive has a terminator
- either internal or external (see p. 3).
4. Set the Priority/ID to any number from 0 to 6 other than 3 (see p. 5).
5. Connect the drive to the EPS-16 PLUS.
6. power on the devices in the proper order -
7. Press Command, then System-MIDI (System on the EPS) and scroll left to the FORMAT SCSI DRIVE command. Press Enter.
8. Set the LOAD DEVICE=SCSI #; to the same Priority/ID number you selected in step 4. Press Enter.
9. Select and enter a unique name (DISK LABEL) for this device. (EPS-16 PLUS only) This is important mainly for removable drives. Press
Enter. 10. Select an Interleave value (see pp. 7-8).
11. Format the SCSI drive. Respond to the prompts which appear by pressing Enter to automatically install the O.S. and set up subdirectories and default macros (see pp. 8-9).
12. Shut off your EPS-16 PLUS and wait ten seconds. Eject the floppy disk. 13. Turn on your EPS-16 PLUS and wait for the system to boot
from the SCSI drive.
SCSI drive first, then the EPS-16 PLUS (see p. 6).
Part 1 - Getting Started
First, a Few Important Notes
Never connect or disconnect the SCSI cable while your EPS-16 PLUS or hard drive is turned on. Serious damage will result.
The EPS-16 PLUS requires a specific file format on any hard disk that it uses, and any drives used with the EPS-16 PLUS must be formatted
exclusively for that purpose. For example, BPS sounds cannot be saved directly to a SCSI hard drive formatted for use with a Macintosh, nor
can the Macintosh store files on a SCSI hard drive formatted for the EPS-16 PLUS. If you are using a SCSI network configuration which
includes a Macintosh and a Macintosh-formatted SCSI drive, make sure that you understand this distinction.
What About Cables'?
There are four types of SCSI cables:
1. Apple/EPS-16 PLUS to SCSI - a 25-pin D-type subminiature connector (DB-25P) on one end and a standard 50-pin male SCSI connector
on the other end. This cable is used to connect an EPS-16 PLUS to a hard drive. Most SCSI hard drive manufacturers supply this type of cable
with the drive.
2. SCSI to SCSI
drives
together.
3. SCSI to SCSI Extension - a cable with a male SCSI connector on one end and a female SCSI connector on the other. These connectors can
be either the standard 50-pin type or the 25 pin D type. This type of cable is used to extend the length of another SCSI cable. We do not
generally recommend the use of long extension cables.
4. Apple/EPS-16 PLUS to Apple/EPS-16 PLUS
This type of cable can be used to connect an EPS-16 PLUS directly to a Macintosh.
SCSI cables usually come in standard sizes of two feet and six feet The combined length of all the cables in your SCSI network may be up to
six meters (approximately nineteen feet). However, you should avoid cables that approach this limit. Always use cables that are as short as
possible for your connections.
- a cable with the standard 50-pin male SCSI connector on both ends. This type of cable is often used to connect two hard
- a cable with 25-pin D-type subminiature connectors (DB-25P) on both ends.
SCSI Terminators
The SCSI terminator is simply a resistor network on each SCSI signal on the SCSI bus. The terminator prevents reflection or ringing on the signal lines, allowing reliable high speed data transfers.
Warning!
A system configuration (two or more SCSI devices) must have two terminators. Damage will result if more than two terminators are present.
Terminator placement is described below.
Page 3
EPS-16 Plus SCSI Manual –
The terminator is usually implemented in one of two ways; either externally or internally. The external terminator resembles two 50-pin SCSI
connectors mounted back to back and encased in plastic. This type of terminator is plugged into the SCSI connector of the device and then the
SCSI cable is plugged into the terminator. The internal terminator is simply the resistor network integrated into the SCSI device itself, typically
as resistor packs on the SCSI device controller circuit board. The documentation which accompanies the SCSI device will usually describe the
procedures required for installation and removal of terminators. The SP-l/SP-2 SCSI Interface accessory contains internal termination via
removable resistor packs. Note that the EPS-16 PLUS receives power for its terminator from the external device. Any drives used with the
EPS- 16 PLUS must therefore supply power to the SCSI bus.
Connecting your EPS-16 PLUS to a SCSI Drive
Each time you set up or break down your EPS-16 PLUS and SCSI drive system, you will need to connect or disconnect the SCSI cable from
the 25 pin connector on the rear of the EPS-16 PLUS, and probably from the drive as well. Be
careful when doing this to avoid static discharges which could damage either piece of equipment. Also make sure that you do not bend the
SCSI cable too sharply, which could damage some of the small wires inside the cable and make it unreliable. If you transport the system a lot,
it is a good idea to carry an extra SCSI cable, just in case.
SCSI System Set-Ups and Termination Requirements
There are two general types of system configurations. The first consists of an EPS-16 PLUS with one or more SCSI drives connected. Figures
1-3 show the termination requirements for several configurations of this type.
Figure 1
EPS-16 PLUS, 1 SCSI Drive Both units must be terminated.
Figure 2
EPS-16 PLUS, 2 SCSI Drives
The EPS-16 PLUS and Drive 2 must be terminated. Drive 1 must not have a terminator.
Figure 3
EPS-16 PLUS, 3 or More SCSI Drives The EPS-16 PLUS and Drive 3 must be terminated. Drives 1 and 2 must not have termination.

EPS-16 PLUS
Part 1- Getting Started
EPS-16 Plus SCSI Manual
The second type of configuration consists of an EPS-16 PLUS with SCSI drive(s) and a SCSI- equipped computer such as a Macintosh. Figures
4, 5 and 6 illustrate several such set-ups. A few notes on using the EPS-16 PLUS with a computer on the SCSI bus:
Note:
. Position the EPS-16 PLUS and the computer at opposite ends of the SCSI chain.
. Any SCSI drives should be located in the center of the chain.
. Terminators must be present on the EPS-16 PLUS and on the computer only. . All terminators in or on the SCSI drive(s) must be removed.
If your Macintosh has an internal SCSI hard drive, it also has internal termination.

The1vJac andEPS-16 PLUS are terminated internally.
Figure 5

Drives 1,2. and 3 must not have a terminators. The Mac* and EPS-16 PLUS must have termination.
*Some computers may not provide internal termination. For these system configurations, simply terminate the drive that is closest to the
computer and use as short a cable as possible between that drive and the computer.
Setting the SCSI Priority (ID) Number
Each device on the SCSI network must be assigned a different priority. The SCSI priority can range from 0 to 7, with 7 being the highest
priority. The priority of a SCSI device becomes important if two devices are trying to control the SCSI bus at the same time. In this case, the
device with the highest priority will gain control of the SCSI bus.
Part 1
The priority of the device is also known as the address or ID of the SCSI device.
It. is important. that each SCSI device be assigned a different priority or ill number insuring predictable communication between devices.
Since the range of valid SCSI ID's is 0 to 7, a maximum of eight distinct SCSI devices can be connected to the network.
