ZuluSCSI Blaster Quick Start Guide

You've just received your new ZuluSCSI Blaster board from Rabbit Hole Computing. Now what?

Step 1: Prep your SD card.

Load either your SD card or microSD card with a disk image. Make sure that you name it appropriately based on the device it's representing as well as its ID number on the SCSI bus. If you're using a hard drive image, name the image HD0.img, and if it's an optical drive image, name it CD0.iso or CD0.bin and CD0.cue depending on which format it's in.

Plug the SD card into the slot on the ZuluSCSI board.

Step 2: Prep the ZuluSCSI board.

Plug the 50 pin ribbon cable (or adapter), into the ZuluSCSI.

The DIP switch block has three DIP switches:

• TERM: Termination on/off. If your device is the last one on the bus, or the only one on the bus, turn this switch on.
• DBG: If on, produce a debug log to a text file called zululog.txt that gets placed in the root directory of your SD card.
• INITIATOR: Allows you to use your ZuluSCSI to capture an image of all SCSI devices currently in your system. This DIP switch must be on the off position for the ZuluSCSI to be detected as a storage device. If it is accidentally enabled, it will not be detected, and its SCSI ID will likely conflict with the SCSI ID of the SCSI controller of the attached machine.

If your device doesn't provide termination power, such as a Mac IIsi, you'll need to provide bus power to it either connecting power to the 4-pin Molex floppy power connector on your board or alternatively by attaching a USB cable to the port on the front of the board.

If you are looking to mount your ZuluSCSI Blaster internally, the four mounting holes on the ZuluSCSI Blaster board are designed to line up with the bottom holes of any 2.5" hard drive footprint. Any standard 2.5"-to-3.5" mounting adapter can fit the mounting holes on a ZuluSCSI board using M3 screws.

If you want to have an external activity LED, you can populate footprint J304 on the board with a standard 0.1" pin header and run a case LED to this header for that purpose. The cathode (negative) end of the LED is marked by a C on the board.

Step 3: Turn on your device!

Once you've prepared the SD card and attached your ZuluSCSI to the cable and host computer, switch things on and go! Your ZuluSCSI should be recognized by your SCSI implementation and the device will mount images as described above, and you should see your device(s) populate in your system.
