Unix disk images and archiving

I've gotten my '040 Cube's optical drive functioning again and now I want to take the original distribution optical disks for various versions of NeXTstep and make bootable copies of them on more usable media, preferably for storage as disk images and as bootable volumes on another SCSI disk. I was thinking of using another magneto-optical drive, such as my Pinnacle Micro Sierra 1.3GB. I've got enough optical disks to do this and the drive is an external MO. Is this doable? The images will have to contend with up to 256MB of data and must be fully writable to a new physical disk, including all boot information. My '040 Cube is running NeXTstep 3.3 with CAPer, so if I made images I could easily move them on to my main Mac for storage. The distribution disks in question have NS 0.9, 1.0, 1.0a, 2.0, 2.1, and 3.0, as well as a non-bootable disk of 3.2. They've been verified as readable and still containing the OS (on my '040 Cube after being locked). Due to the unknown quality of the OD in my '030 Cube I really don't want to try and boot one on it and I'd like to get them to another media before I lose the ability to read them altogether. Any help would be greatly appreciated. Thanks Jeff -- Home of the TRS-80 Model 2000 FAQ File http://www.cchaven.com http://www.geocities.com/siliconvalley/lakes/6757
