There may be compatibility issues with later versions of DOS such as DOS 5 and DOS 6. Until the 1000 RLX, Tandy 1000s are typically limited to 640 KB main memory, and non-Tandy versions of DOS often reduce the memory available for applications and games. In addition, the hardware detection routine for the installer of Microsoft MS-DOS 6 can corrupt the serial EEPROM of Tandy 1000 HX machines.[22]

As the Tandy 1000 uses the same game ports as the Tandy Color Computer series, the 26-3025 Color Mouse and 26-3125 Deluxe Mouse are compatible with the Tandy 1000, though not all DOS software and drivers recognize them. The Tandy Digi-Mouse requires a separate controller that was available in either ISA or PLUS format. Systems with RS-232C serial ports can use standard serial mice, and later systems, such as the 1000 RL, feature a PS/2 mouse connector.

The Tandy 1000 SX uses a 7.16 MHz 8088-2 processor, has 384 KB of memory (upgradeable to 640 KB on the motherboard), comes with either one or two 5.25" internal floppy disk drives, and has the light pen port (not a serial port) like the original Tandy 1000. An adjustable potentiometer inside the system controls the volume of the internal speaker. The Tandy AX is an SX rebadged for sale in Walmart stores. The 1000 SX comes with MS-DOS 3.2 and DeskMate II on 5.25" 360 KB diskettes.

The TX has a 3.5" internal floppy disk drive mounted in a 5.25" bay with room for an optional second internal 3.5" or 5.25" floppy disk drive. The rear panel has the same ports as the 1000 SX, except that an RS-232C serial port replaces the light-pen port. The memory size is 640 KB, with sockets for an additional 128 KB devoted to the onboard video logic. This extra 128 KB can only be used for and by the on-board video controller, so it is impractical to expand the on-board memory beyond 640 KB if a VGA graphics card is installed. The computer comes bundled with Personal DeskMate 2.

The EX and HX are upgradable via Tandy PLUS cards, and these systems have bays for three cards. A PLUS card connector is electrically identical to an ISA slot connector, but uses a Berg-style 62-pin connector instead of a 62-contact ISA card-edge connector. Other PLUS cards can be installed to add serial ports, a 1200-baud modem, a clock/calendar and bus mouse board, or a proprietary Tandy network interface. Radio Shack later sold an adapter card allowing installation of a PLUS card into a standard ISA slot, such as those in the larger Tandy 1000 models.

The Tandy 1000 HX is an updated version of the EX, released in 1987. It utilizes the same architecture and PLUS cards as the EX, but with two 3.5" bays on the front panel, occupied by one or two 720 KB 3.5" floppy drives, as opposed to a single side-mounted 5.25" bay and floppy drive. It also has Tandy MS-DOS 2.11R in ROM, which can be accessed by starting the computer with no bootable disk. Another improvement over the EX is the addition of a serial EEPROM to store configuration information, enabling similar functionality to later CMOS NVRAMs. By comparison, earlier Tandy 1000 models, like IBM PC and PC/XT systems, use DIP switches and jumpers for startup configuration settings.

In addition to Tandy MS-DOS 2.11R, the HX shipped with Personal Deskmate 2. Most versions of MS-DOS works with the 1000 HX, including DOS 3.x and some later versions; DOS 4.0 is incompatible, and the installer for MS-DOS 6 can corrupt the contents of the serial EEPROM.[22]

The Tandy SL and TL series of computers are updates of the SX and TX, respectively. In addition to offering redesigned cases, the machines offer a more integrated motherboard with improved graphics and sound capabilities while dropping composite video output. The graphics controller supports 640 200 16 resolution as well as a Hercules Graphics Card-compatible, 720 350 mode for monochrome monitors. Sound capabilities now include an 8-bit monaural DAC/ADC similar in function to parallel port sound devices (such as the Covox Speech Thing and Disney Sound Source) but extended to support DMA transfers, microphone input capability, and sampling rates up to 48 kHz. The SL/TL allow the on-board floppy controller, parallel port and serial ports to be disabled, which the earlier models do not.

The SL and TL were shipped with MS-DOS 3.3 and DeskMate 3 in ROM, and feature a serial EEPROM memory chip to store BIOS settings. The machines can also run generic MS-DOS 3.x, 5.x, and 6.x and Windows 2.x and 3.0 operating systems, although Windows is limited to real-mode operations. In common with many PC clones of the era, MS-DOS 4 is problematic and generally avoided.

But despite the lofty promises, the Armata project was mired in financial and technological difficulties that slowed development to a crawl. Today, the Russian Ground Forces have precisely zero Armata tanks, with serial deliveries now promised for later this year. 2ff7e9595c
