MacinTalk is Apple's text-to-speech, or speech synthesizer, extension that allows Mac documents to "talk" their text using a range of computerized voices.
MacinTalk (v1.0.2) was relased on April 15, 1985 and works on Mac OS 1.x to Mac OS 6.x
MacinTalk 2 and MacinTalk Pro (both v1.2) were released in 1994 for Mac OS 6 or 7 and were almost immediately made obsolete by MacinTalk 3.
MacinTalk 3 (v1.4) was released in 1995 and became Apple's TTS standard until OSX and is part of Mac OS 7, 8 and 9.

Note: MacinTalk (1985) is only good for Mac OS 6 or lower and is archived here because a very few and old apps/games require this version to work and sometimes it did not come bundled with them. If you use Mac OS 7 or higher, there is no point in installing any of those MacinTalk versions at all, since MacinTalk 3 ships on the Mac OS installation CD's.
Emulating this? It should run fine under: Basilisk II
