I got the SCSI CDrom in a trade a couple years back and to my surprise other than being well used and a bit dirty it works great. I was able to boot the LEGACY Apple Cd rom and load the OS from it.
The problem I get though is when I go to remove a CD and load a new one by dragging the mounted CD into the trash can I get this error:
I am using Apples universal CDrom driver 5.3.1 from here: https://vintageapple.org/macdrivers/disk.shtml
Version 5.3.2 Doesnt even work with my CDROM
