I'm afraid i am going to be a bit of a bother, but I have a few questions about creating a NeXTSTEP 3.3 CD.

My NeXTStation is effectively out of service right now, and will be until I can get the hard drive in it replaced with another SCSI drive (I have spare drives in several old SCSI Mac clones and one in a Mac external SCSI drive) and figure out a way to get a system installed on it.

I fund a website with NeXTSTEP software images but The 3.3 CDs are in BSD Unix format rather than standard ISO. Many CD utilities will not directly open these images, requiring you to write them as "raw" data. I downloaded the image for NeXTSTEP 3.3

https://winworldpc.com/product/nextstep/3x

I have a 2009 Mac Pro with a disk burner capable of writing CD-Raw format, but there is no clear information about how to do this.

Anyone know where it is explained ??

the actual CD image is a standard ISO file (nextstep_3.3_intel.iso). all other files from your download are images of floppies. I used the dd command to write them back to a 3.5" USB FDD...

non-turbo NeXT computers will need the bootfloppy (3.3_Moto_Boot_Disk.img).

regards,
michael

cmmmmmm....

I downloaded it and it is a 7z file, not ISO.

.7z is a compressed format (7-Zip to be exact). You'll need to use 7-Zip to extract the .iso image from the compressed file you downloaded.

7-Zip Dowloads here: http://www.7-zip.org/download.html

EDIT: The CD image is recognized as an .iso on Windows. You should be able to burn a disc from this image without issue.
