Hi, ola -
All OS 9 install CDs (both retail OS 9 Install CDs and original Software Install CDs for OS 9 that come with a machine) include additional software items that address some of those items. These can be found in the CD Extras folder on the CD; scroll down to locate the folder Universal Access, open it - inside are two control panels and a ReadMe.
The ReadMe gives a brief explanation about the items. To install the control panels, copy them to your hard drive, then drop them into the closed System Folder and restart.
The Sound control panel offers a few items for speaking alert messages aloud.
There is also a Text-to-Speech function built-into SimpleText (the machine will read the document, or a selection from it, aloud); some other programs may also incorporate that feature.
In general, though, it is necessary to use 3rd-party software to set the machine up for someone who has no vision. I'm aware such exists, but am not familiar with any. Perhaps someone who is familiar with such software will post in with info about it.
