“Initiator” is the SCSI term for a “Host Device”, or “The device which initiates communication on the SCSI bus”. For reference, “Target” is the SCSI term for a device like a Hard Drive, CD-ROM, Tape Drive, etc. A Target is the device which the Initiator is attempting to communicate with.
The Initiator can be a Mac, PC, Amiga, SCSI add-in card, etc. It can even be SCSI hard drives on occasion in later versions of SCSI.
This allows you to directly connect your 2023.09a later 50 pin Desktop version BlueSCSI to a vintage SCSI drive and copy data from it without needing a bootable “Host Device”. So you can directly take a “Drive Image” so to speak, straight onto BlueSCSI. Significant changes were necessary to enable Initiator Mode, and it does not work with older hardware versions. It is not expected for Initiator Mode support to be added to other hardware styles due to the higher complexity and manufacturing cost.
Initiator Mode has been tested to copy data between BlueSCSI devices, and a few hard drives have been tested as well. Support for Tape Drives and other Targets is currently unknown, and would require test devices.
Many features and bug fixes are included in the nightly release - including support for the Pico-W.
On your SD card, create a file named
bluescsi.ini with the following contents:
Target to the `Initiator side
Initiator jumper near a screw hole toward the middle of the board (by C21, C15)
Back Feed jumper set, when powered via the floppy power connector or USB-C (2023.09a only). 2023.10a can be powered via MicroUSB on the Pico stick.
TRM_ON by the SCSI connector
On your SD card, there will be a new file named
X is the SCSI ID of your Target device. And the
log.txt file will contain information about the drive’s capacity, sectors read, and an approximate read speed.
To use BlueSCSI as a Target again, the two jumpers must be moved back. Remove the standalone Initiator jumper and switch the other jumper back to the Target side.
Removable devices such as CD’s or Zip disks will eject after imaging. New media can be inserted and will be imaged.
