GIGI Exerciser

This document serves as the User Guide for the GIGI Exerciser, a dial-up test program designed to diagnose the functions of a GIGI terminal. It provides instructions on preparing the terminal for testing, which includes installing a 20mA loopback connector, configuring communication parameters like baud rate, and setting specific terminal parameters. The guide details the procedure for connecting to the exerciser program via a telephone line and running a sequence of eight diagnostic tests.

The tests described cover various aspects of the terminal's hardware and display capabilities:

1. Color Bar Test: Checks the monitor's display of color and grey scale bars.
2. Display Test: Verifies screen functionality by displaying full screens of different colors.
3. Screen Alignment Pattern Test: Presents a crosshatch pattern for screen alignment.
4. Communications Test: Evaluates the 20mA current loop communication port.
5. Writing/Screen Color Test: Exercises writing and screen color options using colored circles on changing backgrounds.
6. Max Vector Test: Tests the terminal's X and Y positioning circuits by drawing lines from a red circle.
7. Vector Generator Exerciser: Checks the vector generator circuitry by drawing and manipulating lines.
8. Keyboard Exerciser Test: Verifies the correct operation of all keyboard keys through interactive input.

Each test explanation includes its purpose, expected displays, and troubleshooting tips for identifying and resolving issues. The document concludes with instructions on how to properly disconnect the terminal from the computer after completing the tests.
