In my own efforts to restore a PowerMac 7500, it took a fair amount of time to get the right CD-ROM extension and Drive Setup versions to make it possible to use the non-Apple branded DVD-ROM and hard drive I had. Trying to help fellow enthusiasts, I'm uploading the floppy image with these versions for any other classic, SCSI based, Macintosh when you can't source working Apple-branded/manufactured CD/DVD-ROM or hard drives. This floppy image contains the following utilities:
Apple CD-ROM Extension vD2-5.3.1 (11/18/1996 release date)
Apple Drive Setup v1.7.3 (5/15/1999 release date)
Aladdin Expander 5.5 Installer
The CD-ROM extension is a bugged version from Apple that does not perform the Apple drive firmware check and works with non-Apple SCSI drives. The Drive Setup is another bugged version that allows the partitioning/formatting of non-Apple SCSI hard drives. Finally, Aladdin Expander makes it easier to install the necessary software to expand compressed images without needing to uncompress them prior to upload/copy.
Macintosh v7.1 - v8.5 (v9.0 and above no longer need this)
