Diagraph 3.5

Diagraph, from Computer Support Corporation, is a program that lets users assemble presentations, charts, and graphs from a very large library of predefined symbols.

It features a very large symbol library, detailed high resolution vector-based graphics, shading, complex curves, symbol manipulation, scalable vector based fonts, and supports output to plotters and film recorders.

Although symbols can be manipulated in a number of ways, it does not include freehand drawing. Automated business graphing was included in a separate companion product, "Picture Perfect".

Diagraph competed against products such as Diagram Master.

Diagraph was commonly distributed with HP computers. The user interface style includes on screen "softkeys" that were popular with HP.


Release notes

This version is intended for IBM PC and compatible computers. It supports IBM CGA, EGA, Hercules, HP Multimode Video Adapter 45981A, HP Multimode Color Adapter 45984A, HP Enhanced Graphics Adapter 45983A, Persyst BOB Graphics Board, and the Tecmar Graphics Master.

The Diagraph application must be run through the "CSAM" shell. The CSAM disk also contains the copy protection.

Run configure on the CSAM disk to specify the video mode, and which disks to search for the Diagraph application files.

This disk set was set to search the "C" drive. You may copy all of the files to a folder on the C drive, and then run CSAM with the CSAM floppy in the A drive as a keydisk.

The manual describes a way to install the product so it does not need a keydisk, but apparently the files needed are only on a disk that is mailed to the user after registering the product.

The "instz" program seems to be only for a specific zenith machine type.

Important: This software is copy protected, and no unprotect is known to exist.

Copy protection method: Superlok.
