Disk No: 2019 Disk Title: Speaker/HexEdit/DiskTest PC-SIG Version: S1 Program Title: SPEAKER Author Version: 1.0 Author Registration: $10.00 Special Requirements: Graphics adapter, graphics printer. This program performs Thiele-Small alignments for any given speaker in a vented enclosure. This means it will determine the optimum cabinet and vent size for the driver entered. It requires the Thiele-Small parameters for the driver (available on most data sheets) to perform the analysis. It will graph the speakers response on screen along with all the calculated results. It can also graph the speakers thermal and displacement limit curves and a simulated square wave response. The user can request the screen to be printed. The program includes a data file that contains almost every driver made by JBL. New drivers can be added to this file from within the program. Program Title: HexEdit Author Version: 1.0 Author Registration: $10.00 Special Requirements: None. This program allows the user to view, modify, and write any file. It edits the file in hex so it can edit .exe, .com, or data files. It provides basic editing functions such as insert, delete, search, insert/overstrike mode, load new file, save, and a 100-level undo. Help is available with the F1 key. It can edit any size file up the limit of available memory. Program Title: DiskTest Author Version: 2.3 Author Registration: $10.00 Special Requirements: None. This program performs read and write tests on any floppy or standard hard disk. If it detects any errors, it shows the exact error that occurred and the sector in which it occurred. When finished it shows how many errors were corrected by retries or recalibration. It allows the user to specify to starting and ending sectors to test and the number of test loops. It allows the user to choose read-only, write- only, or write and read testing. The user provides the data pattern to be written.
