Share your knowledge on these two classic MPCs

I recently picked up a vintage AKAI MPC3000 and am attempting to bring it back to life.

INITIAL ASSESSMENT:

1. System begins to boot up at POWER ON
2. System Version 3.11
3. Screen Displays "Loading Files" and progresses for about 15 seconds then ..
4. Screen Displays "Searching SCSI for Hard Disk" and HANGS UP
5. System does not respond to SOFT KEY 4 <CANCEL> input

RESEARCH
1. Symptoms indicate fuse F901 on the SCSI PCB may be blown

NEXT STEPS
1. Checking for continuity across fuse F901 on SCSI PCB

I'm brand new to the AKAI MPC3000 but have a background in electronics service and repair.

Any suggestions would be appreciated!

Thanks

Everything you're doing so far is correct and more than what most people do that post here with the same questions.

Do you own any scsi devices that you can connect to the DB25 on the back?

Reason why I'm asking is that for the sake of troubleshooting, I connect a SCSI ZIP drive or any SCSI device that I can provide my own termination to, so I would not be relying on the onboard SCSI card and termination fuse for that. I've found that it is an interim way to resolve the issue so I can get back to making beats.

Ultimately, swapping out the scsi fuse is the first and most common thing that resolves this issue.
