I got the image from the Vintage Computer Files KDX server.
And yes, same place every time, or just about. I will try a different CD drive.
Edit: It was the CD drive. I got it to boot into the actual A/UX operating system now (it ejects the floppy), but it says it cannot locate any disk drives, and that I should check the SCSI connections, termination, etc.
I am not very familiar with SCSI so I really don't know what I should do.
The hard drive is a Quantum Atlas II 4.5GB. The CD drive is an Apple 12x CD-ROM.
