The Installer will ask for the PlainTalk Disk 5 or the Introduction to Speech
disk if you try to install PlainTalk from the PlainTalk diskettes.
You must install PlainTalk from the System Software diskettes that came with
your AV computer. Do NOT attempt to install PlainTalk from the PlainTalk
diskettes.
To install PlainTalk, you must perform a custom System Software install. To
do this, follow these steps:
1) Boot your Macintosh with the Install Me First diskette.
2) Select a custom installation.
3) Select PlainTalk only, then click Install. Swap diskettes as directed by
the software.
This will install all the necessary PlainTalk files without asking for the
nonexistent disks.
