It is SCSI1 compliant and is the most reliable because it is genuine.

This board is made for X68000 personal workstation series (except CZ-623) and is attached to I0 expansion slot.

It can be used with SCSI MO drives, hard disks or CD-ROMRW units.

Small Computer System Interface (SCSI) is the standard for data exchange between computer systems and peripherals.

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

Switch the power switch to Off position, unplug the power cord and proceed with the installation.

Devices which are connected to SASI interface and those which are connected to SCSI have different representation IDs.

As described above, SASI can handle up to 16 devices, SCSI can handle up to a maximum of 7 devices.

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

Jumpers JP1, JP2 set the interrupt priority for 68000 CPU to level 2 or 4 (Source I0 is available in two levels) and the board interprets from the jumper settings which one to use.

If you own the software, interrupt handling is set as follows.

Set the priority level of the interrupt request signal with jumper JP2, set the interrupt priority level of the allowed signal with jumper JP1.

If you are planing to use the CZ-6BS1 in conjunction with CZ-6BE2, CZ-6BE4, CZ-6BF1, CZ-6BM1, CZ-6BP1, CZ-6BC1, please populate IO slot 1 before installing this board.

This board can also be used in conjunction with CZ-6BG1, CZ-6BU1, CZ-6BL1, CZ-6BL2, CZ-6BN1 boards.

Since the introduction of IO expansion box (CZ-6EB1) we ship two brackets.
