As the processors on the TL-series are socketed, it is possible to install 386SX or Cyrix 486SLC-based processor upgrades, though the benefit of installing more advanced processors is limited beyond merely providing a speed increase due to the computers' XT-based architecture, and their resulting inability to access extended memory above 1 MB.[30]. Using specially-designed aftermarket cables, it was possible to connect non-Tandy printers to the system. The Tandy 1000 SL and SL/2 feature an Intel 8086 processor running at 8 MHz. The Tandy 1000 SX and TX were upgraded versions of the original Tandy 1000, utilizing a similar chassis. $119.99. Like the original Tandy 1000, the EX and HX do not have a built-in DMA controller, though one can be added using the PLUS memory expansion board. £289.09. The Tandy 100 was actually a computer made in Japan by Kyocera. Tandy used the main memory for graphics, as a result most programs require 640k or 768k to run. 1983: Radio Shack unveils the TRS-80 Model 12 at the CP/M '83 Show. The market is big". The TRS-80 launched in 1977, before the home computer market had really exploded. or Best Offer. For the original Tandy 1000, the designers omitted a DMA controller because the PCjr does not have one, and they believed that those who needed it would add it with additional memory for the computer; they omitted the RS-232 port because all Tandy printers use the parallel port and, they believed, most customers would use internal modems. Following the original Model I and its compatible descendants, the TRS-80 name later became a generic brand used on other technically unrelated computer lines sold by Tandy, including the TRS-80 Model II, TRS-80 Model 2000, TRS-80 Model 100, TRS-80 Color Computer and TRS-80 Pocket Computer. The SL/TL and later used a more directly PC/XT-compatible keyboard protocol, and the 1000 RSX used a PC/AT and PS/2-compatible protocol. The keyboard connectors of the RL-series, while similar to and mechanically compatible with PS/2-style connectors, were not fully compatible with typical PS/2 keyboards, as the keyboard uses the XT keyboard protocol. Tandy (Radio Shack) is a maker of homecomputers between 1977 and early 1990. Prices started from $999 for the diskless version. Price is US$3200. As with the keyboard, it was compatible with the older TRS-80 and Tandy color computer models, but not compatible with the IBM standard 15-pin male game port. It utilized the same architecture and PLUS cards as the EX; however, one obvious difference was that it offered 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 with the EX. Tandy Graphics or TGA) and three-voice sound hardware of the Tandy 1000. Manufacturer : Radio Shack - Tandy Type : Computer The parallel port was bidirectional, a first for the Tandy 1000 series. These programs include a text editor, a telecommunication program, which uses the built-in modem (300 baud), and a rather good version of BASIC (no big surprise there). The Tandy Digi-Mouse was also available, which required a separate controller that was available in either ISA or PLUS format. $85.00 shipping. The DAC could be used to emulate the Covox Speech Thing via MS-DOS device drivers for limited sound support. 1983: Tandy releases the TRS-80 Model 2000, which uses the Intel 80186 microprocessor. The ACUMOS VGA graphics could be software-updated with Cirrus Logic BIOS (via MS-DOS driver) to allow VESA/SVGA to function in Windows 95, as the Windows 3.xx Tandy VGA drivers were insufficient for Windows 95. In 1987, they partnered with Diamond and through Radio Shack sold the Diamond Trackstar 128 series Apple IIe compatibility board for $399, and offered free installation in their Tandy 1000 series. By comparison, earlier Tandy 1000 models, like IBM PC and PC/XT systems, used DIP switches and jumpers for startup configuration settings. The TRS-80 (which became known as the Model I after the Model II was introduced in 1979) was created by Don French and Steve Leininger. The Tandy 1000 was the first in a line of IBM PC compatible home computer systems produced by the Tandy Corporation for sale in its Radio Shack and Radio Shack Computer Center chains of stores.

Radio Shack TRS-80 PC-2 Vintage Tandy Programmable Pocket Computer Case Ref Card. Help support the museum by buying from the museum shop. It is sure to put a whopping dent not only into PCjr sales, but into sales of the PC 'senior' as well". InfoWorld in 1985 disapproved of the computer's high cost of accessories ("and you'll find that the Tandy 200 has more accessories than a Barbie doll"), but called it "a big step up from the Model 100 for someone who needs a note-taker or spreadsheet on the run".[14]. For most Tandy 1000 models (other than the compact EX and HX) that did not come already equipped with a hard drive, Tandy offered hard disk options in the form of hardcards that were installed in one of the computer's expansion slots and consisted of a controller and drive (typically a 3.5-inch MFM or RLL unit with a Western Digital controller) mounted together on a metal bracket. The original line was equipped with the Intel 8088 CPU, which was later extended to faster clock speeds and also the 8086, 80286 and toward the end of the line with the RSX, 80386SX processors. 26.3002; Super VGA with the Tandy 1000 RLX; Trs-80 Model 4p 80x24 screen issues (gate array motherboard) TRS-80 Model II acquired. Similar to the IBM XT 286, it featured a 16-bit-wide memory bus, although the on-board peripherals and ISA slots were 8 bits wide.[28]. Originally, Tandy offered computers manufactured by Tandon Corporation, and then started producing their own line of systems. Before its release, mobile computers, such as … [9] Software companies of the era advertised their support for the Tandy platform;[15] 28 of 66 games that Computer Gaming World tested in 1989 supported Tandy graphics.[16]. Since IBM discontinued the PCjr soon after the release of the 1000, Tandy quickly removed mentions of the PCjr in its advertising while emphasizing its product's PC compatibility. Tandy Radio Shack wanted to compete in the education, school and home market, which was dominated at the time by the Apple IIe. 1985: March - … $299.95.
