Introduction
PLATO is an acronym for: Programmed Logic for Automated Teaching Operations.
The TI-99/4A Plato Cartridge was the ONLY computer system that allowed an independent collection of Plato Courseware to be accessed on the computer; the Atari Plato Cartridge only allowed the computer to act as a Plato Terminal where the computer connected to a mainframe via a telephone connection.
In mid 1983 TI and Control Data struck a deal to release the PLATO courseware for the TI-99/4A. Until this time PLATO was only available to large businesses, universities and government offices, as it ran on main frames.
TI released 108 courses with 481 programs for students in grades 1 through 12. To be able to use the PLATO system you needed: TI-99/4A console, Disk controller and drives, memory expansion, and of course the PLATO interpreter cartridge.
Did you know
that there is a whole community of TI-99/4A hobbyist that are avid
PLATO enthusiasts?
Many of the
TI-99/4A enthusiasts over the years have acquired the entire TI-99/4A
Plato System which consists of a Plato Cartridge & 481 90K 5¼
inch disks.
There are now
even TI-99/4A emulators that run on IBM PCs running Windows 7 that
also execute the Plato System as it was executed back when Control
Data sold the product.
It may be a
curiosity resource that you might want to obtain and
demonstrate an actual Plato System from around circa 1983 in action!

Now the users can see what a nice collection of Plato Software that the TI-99/4A had available for the machine as compared to other micro computer users.
Conversely, they can actually load a Plato Terminal program onto their current computers and then join the www.cyber1.org site to then experience Plato from a mainframe as it was back in the mid 1980s for a comparison between the two methods of accessing Plato Software.
