ARABART - Demo

Written in 1991

Language: Assembly

First written in 1991 and updated till 1993, Yasser wrote the ARABART library which added Arabic support in the DOS graphic mode which allowed him to create programs that display Arabic in different fonts, colors and styles. The library supports auto-shaping (choosing which letter form to use, ie. connected from the beginning, both sides, or end). This program serves as a demo to showcase all the capabilities of the ARABART library.

Digi-Test

Written in 1993

Language: C++, Assembly

This software is a part of Yasser's graduation project which involved the simulation and testing of digital circuits. This software is the GUI of the graduation project, running on DOS. Additionally, this graduation project included a custom made board and interface with the computer in order to analyze, simulate and reveal faulty ICs. Despite still being able to construct and simulate circuits, due to lack of hardware we cannot view the Truth Table generated or analyze the circuit for faults. To see the circuit used in the graduation defense, load the file "KEMYAM".

Keypress	Effect
F10	Access the top menus.
INS	Begin drawing a wire/connector between 2 points.
DEL	Delete the component currently under the cursor.
