About the ECHOshk.bin archive

File Type: ShrinkIt archive
Status: Freeware 

It's just a larger, or Extended, Vocabulary disk. It's used the same as the
smaller 800 word vocabulary disk that fits on the 5.25" disk. Think of it as
"clipart" for the echo card and whatever programs the user wants high quality
speech. Both versions work swell off of a hard drive.
