Updating powerbook cd drive
Often the simplest way is to start an FTP server on the Mac running a modern Mac OS X release and then using an FTP client like Fetch or Archie on the much older Mac to directly download the packages to the older computer.
That would require some local networking however, but if the older Macintosh is directly connected to the internet already they could always just download the package files directly too.
This will format the drive and prep it for the next step.
Next, launch Super Duper, and set it to clone your Mac's hard drive to the SSD.
But if you don’t want to commit to local emulation, you can also run Hypercard in retro Mac OS System in a web browser or run a web browser based Mac Plus emulator with Mac OS Classic too.

The following links may be helpful for that purpose, though keep in mind all of these are not officially supported by anyone, they are not sanctioned by Apple or any other developer, and most of the links are to what is considered abandonware software – meaning it’s old, no longer updated, or supported.
