The final version of the Model 4 is the Model 4D (Radio Shack catalog number 26-1070), first sold in 1985. It is a Gate Array desktop machine featuring dual TEC FB-503 disk drives[28] with a capacity of 360KB each (double density sectors, 40 track, double-sided). Rather than using a lever-style latch as had previous Model 4 drives, these drives use a twist-style latch that provides for more reliable clamping. They are half-height drives mounted with full-height faceplates.
The DeskMate productivity suite is bundled with the 4D. It supplies simple applications including a word processor, filer, spreadsheet, calendar, and mail manager.
Later Misosys, Inc. updated LS-DOS 6.3 to support dates through December 31, 2011 (as well as a few other enhancements). The Model III LDOS 5.1.4 was also updated to version 5.3, supporting the same feature set as LS-DOS 6.3.[29]
The Model 4D is the last computer descended from Radio Shack's original Model I from 1977 but it is not branded as a Radio Shack product. The badge mounted on its front cover brands it as the "Tandy TRS-80 Model 4D". This change in marketing resulted from Tandy corporation's desire to enhance its stature in the marketplace, because it was perceived by some in the computer press that the old "Radio Shack" moniker connoted an image of inferior quality. The Model 4D is the last computer to bear the "TRS-80" name. It retailed for 99 at its introduction in 1985. During 1987–1988 the retail stores removed the Model 4Ds from display but they were kept in the yearly computer catalog and were available by special order through 1991,[30] when they were closed out for 9. Parts and repair service remained available for several years longer.
