MS-DOS 2.11, DeskMate 1.0, and a keyboard with the same layout as the Tandy 2000's were included with the computer. Like the PCjr, the Tandy 1000 motherboard did not supply DMA, but unlike that system, it could have DMA added with a memory expansion board. While the Tandy 1000 had three XT-compatible expansion slots, early Tandy memory upgrade boards took up two of the slots to get to . Because the slots were inches in length instead of the PC's 13 inches, full-length cards did not fit, but reviewers noted that the many built-in hardware features reduced the need for cards.
