I am still running some DOS programs but they run in DOSBOX that W/7 still supports. (Not the command prompt, a DOS emulator). XP would run those natively except it had problems with the extended memory manager in dBase. Occasionally I also had a glitch in the disk management. DOSBOX fixes all of that. I just created an entire DOS environment that looks and acts like one of my old 386 machines but is a whole lot faster.
