NFG Games + GameSX

This is a genuine Sharp Corporation SCSI board. It is SCSI1 compliant and is the most reliable because it is genuine.

1. Product Overview

1-1 Overview

This board is made for X68000 personal workstation series (except CZ-623) and is attached to I/0 expansion slot. It can be used with SCSI MO drives, hard disks or CD-ROM/RW units. Small Computer System Interface (SCSI) is the standard for data exchange between computer systems and peripherals.

1-2 Features

• Mass Storage Device with SCSI interface: up to seven devices can be connected in daisy-chain.
• Data transfer rate is faster than for SASI interface.

2. Package contents

When unboxed, make sure that you have received the following things:

• SCSI brackets
• Floppy disk with SCSI software
• I/O board
• Instruction manual
• Waranty voucher
• List of customer services

Please keep packaging materials in safe place.

3. Installation notes

• When installing SCSI bracket pay attention to which one you need, because desktop models such as CZ-652C, CZ-653C, CZ-662C, CZ-663C have different dimensions. Switch the power switch to “Off” position, unplug the power cord and proceed with the installation.
• Use this device only after installing the bracket and reading the instruction manual which came with your SCSI device.
• When not in use for long periods of time, remove the device from computer and put it into the supplied anti-static bag to protect it from electro static discharge.
• If the device has stopped working, please contact the nearest customer service center.
• The SCSI interface and X68000 integrated SASI interface, except for the CZ-623C, is different and SCSI interface is seen by Human68k as another interface that can interchange data betwean both interfaces. Devices which are connected to SASI interface and those which are connected to SCSI have different representation ID's. For example, SASI (HD0 - HD15) and SCSI (SCSI0 - SCSI7). Device may be marked with ID that it represents.
• ID numbers for SCSI and SASI devices differ and they are physically different interfaces. As described above, SASI can handle up to 16 devices, SCSI can handle up to a maximum of 7 devices. A maximum of 23 devices can be connected in total.

This board was used without problems even after connecting the same amount of devices to SCSI and SASI interface at the same time.

4-2 Jumper settings

Jumpers JP1, JP2 set the interrupt priority level for 68000MPU to 2 or 4. (from the I/0 Surotsuto is available in two levels) switches for setting whether to use either. The included software interrupt processing in the setting of the switch so jacket does not use is optional. (Factory default is set to level 2 for a bottle.)If you own a software interrupt processing is set as follows. Set the priority level of the interrupt request signal switch jacket JP2, set the interrupt priority level of the signal allowed by the jacket Switch JP1. The priority level can be selected as a Level 2 or Level 4.

Kyung-level priority interrupt request signal will be activated and allowed is set to the same level. At level 2 interrupt request level, such as how to use it at level 4 and level interrupt is not allowed.
