If you have the Spyrus connected and set correctly.
You will need to format and make active the Spyrus first.
Select on the MPC3000, DISK, OPTION 9 and then the option to make a SCSI disk active.
Set the MULTI SECTOR TRANSFER mode to OFF.
Now on the MPC3000 select DISK, OPTION 9 and then the option to format a SCSI device.
Select AUTO for the SCSI target.
Press soft key one to start the format process.
The MPC3000 at this point will scan the SCSI bus for a suitable target.
If the Spyrus is visible to the MPC3000 on the SCSI bus then it should flash a couple of times and formatting will continue.
An important note here regarding Spyrus drives.
Many models rely on the active power termination supplied to the SCSI bus via an MPC3000 in order for their termination power circuit to work.
If the Spyrus is not visible to the MPC3000 at all, even if seemingly connected and terminated correctly ...
It's a strong indicator that the SCSI fuse on your MPC3000 SCSI board is blown.
