Termination issues with BlueSCSI v2 on Amiga 3000 external DB-25 port #140

I have an internal blueSCSI v2 (50 pin ribbon cable version) and an external BlueSCSIv2 (DB-25). Both work trouble free with a Mac LCIII (connected to the internal and external SCSI ports respectively).

When I try to connect them to an Amiga 3000, the internal version works fine if connected to the internal SCSI, but I'm having some issues when trying to use the external DB-25 port. Note that I have a terminated HDD inside the internal amiga SCSI (providing termination on that end) and the termination resistor packs are also removed from the amiga PCB (to allow connection of external devices).

I guess the root cause for the onboard termination not working on either device should be the same. It if would be fixed on the internal version, then that would also help getting the external version to work.
