README file for ViSta for MacOS.

===============================================================
Hardware and Software Requirements
===============================================================

There are two versions of ViSta for MacOS. One is for the PowerMac and
one for 680xx Macintoshes with math processing unit. For 680xx Macs, we
recommend a 68040 processor which incorporates a math processing unit.
A Mac with a 68030 plus 68881 math coprocessor is minimally acceptable.
There is no version for Macintoshes without math processor, although
coprocessor simulation software such as SOFTFPU can be used. A color
monitor is required (17" or larger recommended). Both versions require
System 7 or later, 3 MB of free hard disk space and at least 8 MB of
RAM (10 for the PowerMac). Each version includes XLisp-Stat and ViSta
in a single download of about 1.5 Megabytes.

===============================================================
Installing ViSta from the Downloaded file.
===============================================================

The download that you receive will be a single self-extracting-archive
(.sea) file containing all of ViSta along with the portions of the
XLisp-Stat system that are needed for the version of ViSta for MacOS
that you selected.

Once you have downloaded the .sea file you extract ViSta from it by
double-clicking the file. ViSta will install automatically and will be
ready to run. Just double-click the ViSta icon.

Read the welcome message. It tells you how to configure ViSta.

=============================================================== 
ViSta is a work-in-progress
===============================================================

ViSta has been used in introductory statistics courses, in
undergraduate and graduate courses in multivariate statistics, and in
graduate courses on research in computational and graphical statistics.
ViSta is sufficiently mature for these uses and provides a complete
range of capabilities for the more advanced courses. Some capabilities
needed for introductory statistics (frequency tables and graphs, for
example) are still missing.
