Turbo XT BIOS
QuickBASIC 4.5 is the most popular version of Microsoft BASIC for DOS, probably due to the friendly (but not overly complex) IDE and "online" help system.See the patches section for additional patches and utilities for this compiler.Note: QuickBASIC is no longer sold or supported by Microsoft. Therefore, I am making it available for download here. If you represent Microsoft and want this download removed, please contact me.
