Apple Mac OS 8 was another major overhaul of the OS from the earlier Mac OS 7. It added a new Platinum visual theme, a multi threaded Finder, better virtual memory, and many customization options. 8.5 and later require a PPC CPU. It was followed up by Mac OS 9. Apple Startup 9.2.1 repairs problems that may occur when Mac OS 9.1 and Mac OS X are on the same partition and a version earlier than Startup 9.2 has been used. The Utilities folder on the Mac OS X CD contains Startup Disk version 9.2, the control panel you use to select the startup disk for your computer.
You could create a Mac OS 9.x bootable utilities disk, from the OS installation on the hard drive - if you know what you're doing. You'd need a third-party software like 'Toast' to recognize the third-party CD-R/RW burner and write the bootable disk. You'd need to determine which assortment of System Folder files were necessary to copy, to create the abbreviated System Folder on the bootable CD. You can burn data CDs with USB 1.1, but you'll be limited to 4x burn speed - which is slow, but not intolerable. If you can borrow or buy an older USB CD-R/RW drive that's backward-compatible with your iMac's USB 1.1 bus speed, you could accomplish this. The alternative is to check eBay for Norton SystemWorks 1.0 for Macs, which shouldn't be expensive. The disk is bootable and would enable you to run DiskDoctor, and then Optimize the disk. This consolidates/moves all data on the drive and arranges it by file type, and then leaves contiguous free space at the end. https://awayrenew771.weebly.com/adobe-dreamweaver-cs6-mac-free-download.html. You can select to wipe the free space with a security wipe, to remove all traces of your personal data. The average user won't be able to recover it. Otherwise, you could check eBay for a Mac OS (retail) universal installer disk for OS 8.1, 8.5, or 9.x and just reload the software to a newly-reformatted hard drive. If you want to sell it, you may have to spend a little $$ to do so. Considering the negligible value of a working 233 MHz iMac now, you'll likely not make a profit. I suppose that's why so many just remove the hard drive and e-Cycle old computers.

By default, your Mac starts up from its built-in hard disk, but a startup disk can be any storage device that contains an operating system compatible with your Mac. For example, if you install macOS on an internal or external drive, your Mac can recognize that drive as a startup disk. You can then follow the steps in this article to start up from it.

When you use Startup Disk preferences to select a startup disk, your Mac starts up from that disk until you choose a different one.
Choose Apple menu > System Preferences, then click Startup Disk.

If you're in Startup Manager and can't see a third-party startup disk, the startup disk could be using Option ROM firmware.

To do that, press Option-Shift-Command-Period while in Startup Manager. If your startup disk appears, do that each time you want to start up from it or from another disk connected to it.
