The Installer required to install the EtherTalk drivers are located on the
Network Products Installer Disk, which is located in the "Read Me First"
manual that came with the Macintosh IIsi.
There isn't an updated installer for the CD-ROM drivers, but there is a
workaround. Just drag the following files into the System Folder:
- Apple CD-ROM
- Foreign File Access
- Audio Access
- CD Remote INIT
- ISO 9660 File Access
- High Sierra File Access
Use Font/DA Mover to install the CD Remote desk accessory, then restart the
system.
