    Hi. Did you complete the S-750 SCSI issue? I’d like to do exactly same thing with my S-750, so any piece of advice, part numbers and so on are very welcome. Best regards, Mattias

      Hi, I have not completed the S750 SCSI changes as I have focused on getting SCSI2SD working on my S-760 and W-30. But its next in the back log and I will post details. Thanks Rob

    I have an S-770 with a V6 SCSI2SD mounted internally. I’ve been struggling trying to get CD-ROM images onto the virtual drives for weeks now. It doesn’t seem to be very straightforward!

    If you or anyone else ever figures it out let me know!!

    Good luck with the renovations!

    • Hi Matt,

      You will have to burn a CD ROM ISO image directly with a Mac, using terminal and DD command. This is the only way I got my Emu’s to read CD ROM images directly from an internal SCSI2SD. The E-mus can also read Roland disk images, so this should apply to the Roland S-770.

    i want to re new my s770 (lcd) display. Does it need the black (k) and gray (a) wires for power or is powered from the flat cable.

    any help would be appreciated.

      Only needs the flat cable if you use led or oled display.

  • would love to hear how this turned out!

    is there a particular firmware/OS version that is required to run SCSI2SD on the S700 series?

      The SCSI2SD drive plugged straight into the S760 and worked perfectly. It was formatted and loaded with 2 sample cdroms by a third party.

    I was on the same quest with an S-750, to install the SCSI2SD (v5.1) in place of the floppy drive. I found those same, open 50 pads on the motherboard, and found that they were matched with the 25 pin connector on the SCSI bus. I matched all 18 of the pins, and directly soldered a 50 pin ribbon to connect the new drive. After testing, it didn’t work! I checked all the connections I made, and measured continuity through the drive, and to the DB25 connector. It should have worked!

    On start up, it will either get stuck on the initialization message, or will move passed that and get stuck after the Wave Memory check. The only way I’ve been able to get it going again with the SCSI2SD is by reinstalling, and powering, the 3.5” floppy drive with no disk. It will then appropriately map the drive and fully boot up. I also have to connect the DB25 to the SCSI2SD. It doesn’t want to work with the new ribbon I installed.

    I’m curious what else I could try? While I’m glad I was able to get it working again, I’m kind of bummed I couldn’t install the new drive in place of the floppy drive.

    I haven’t removed any of the new wiring. My guess is that the problem has to do with termination, or drive mapping.

    I’m open to any suggestions!

      I just found this. Many of you may have already seen this as well. You need to translate to English.
      I’m going to try this on my S-750.

      Did you follow the same pinout as listed above in this article? If not can you provide your pinout?

        I never completed the SCSISD PCB for the S750 and sold the S750 this year. Too many projects to complete! Rob

  • Do you need the turbo rom?

      Hi, no the S750 has 18MB of RAM. But many thanks for the offer of help! Rob

    Hi, I was wondering if you had any tips for troubleshooting an S750 that freezes on wave load. OS loads from SCSI fine.

      The sampler has the full 18MB memory, I’m thinking of trying it with just the 2MB, do you think this is a good idea?

        Hi, Yes, good idea!
