Confirmed - working with ROLAND S-750 Sampling Machine (MSX)

[algeist]

It is a professional sampling machine which is based on msx computers. Uses 25pin DIN. It worked flawlessly.

NOTE:
Although the version [v1.1-20220404] works completely fine,
the later versions both [v1.1-20220620] and [v1.1-20220628] freezes while SCSI SCANNING.
The CD-ROM (optical disk) option is highly needed with these musical instruments and I'm planning to debug the code.
Is there a more direct & easy way to make stm32 debug its output to log.txt or debug.txt rather than changing the code and rebuilding it ?

Hi there, I've recently bought a BlueSCSI for use with my S750. I haven't managed to get it working yet but as I bought it only the other day, I'm sure the firmare will be current. Have you had any luck using any firmware other than the one mentioned in this thread? The latest is from September as you are most probably aware.

I managed to work out what was wrong, I needed to power the BlueSCSI by usb before turning on the S750, everything seems to be working fine now on the most recent firmware of Sept 22.

Hello, sorry for delayed comment.
I've only tried versions up to [v1.1-20220628]. So I don't know the results of the recent updates, although I'm aware of them. :)
If you're using s-750 with only BlueSCSI (as one or more harddisks) than usually you won't get much problems. Usually musicians need to copy their original CD-ROM's to their harddisks for quick and responsible access. So there is a need for three devices chain: "(real)CDROM Player <-> BlueSCSI <-> S750" . This configuration is highly problematic but I managed to achieve a working system and copied some cdroms as HD images. (The Roland Units have options to do this inside)
The real need is for two devices but BlueSCSI having two roles as both harddisk and cdrom devices.
That is what I've mentioned in the first place. I hope the latest version provides sufficient SCSI compatibility. As far as I know, Roland S750 uses SCSI 1. (and also S-760)
