Obtaining and Installing Triangle

DOS Triangle is a discontinued program. However, since there are still many blind DOS computer users in the world, we are happy for anyone to download and use the program, but it is no longer supported by the Science Access Project. Most of the SAP files have not been updated and contain information that is now outdated and links that no longer work or link to what is described. Oregon State University accepts no responsibility and assumes no liability for use of this program.

This page provides a link to download the DOS Triangle program and instructions on installing it.

Download the TA-SETUP.EXE installation file. and save it either on your hard drive or on your floppy drive. Run this installation file either in DOS or Windows as described in this section.
