emusonacid! legacy

My Toshiba SCSI CD Rom drive suddenly stopped working so I've just bought a replacement.
However, it turns out that this model is only tested to work for the ESI not EOS ! It's on the official Emu list of known drives and powers on and I'm able to read what's on the disks, but it won't load with my Ultra and that's as much as I know.

It's a CD ROM 40 X Toshiba XM 6401B.

You'll need an external case and power - this is just the drive.
