By comparison, earlier Tandy 1000 models, like IBM PC and PC/XT systems, used DIP switches and jumpers for startup configuration settings. A single half-size 8-bit expansion slot was available. Watch. [7] Disk-based Model 4s had 64 kilobytes of RAM standard; an optional bank of additional 64 kilobytes was accessible to applications software using bank switching technology. Compatibility was fairly good and allowed Tandy 1000 owners to run most Apple II software on their Tandy 1000 machine for less than the cost of owning separate IBM PC and Apple II systems. Tandy! $48.66 shipping. The major difference was the 80286 CPU clocked at 8 MHz. 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]. Tandy Computer TRS 80 - Model 40. or Best Offer. Radio Shack Tandy TRS-80 64K Extended Basic Color Computer 2 CIB Bundle. It is sure to put a whopping dent not only into PCjr sales, but into sales of the PC 'senior' as well". A cat resting on a Tandy 1000 EX computer, replacing the light pen port of previous models. 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. No. Radio Shack released one of the first home computers, the TRS-80 Model I, in 1977. Radio Shack often offered a package bundle with a Tandy 1000 computer, CM-5 budget monitor and DMP-130A printer.

The RL and RL/HD featured a surface-mounted 9.54 MHz 8086 processor, 512 KB of RAM (expandable to 768 KB to provide 128 KB for video and 640 KB conventional memory), a DB-25 unidirectional parallel port instead of the edge-connector ports, and the SL's enhanced graphics and sound. The T-1000 was Tandy’s last attempt in the home computer market. It had a 10 MHz 286 (surface-mounted) and 512 KB of RAM, and unlike other 286-based Tandy 1000 models, it supported 384 KB of extended memory when RAM was expanded to the maximum 1 MB. The combination of the acoustic coupler, the machine's outstanding battery life (it could be used for days on a set of 4 AA cells), and its simple text editor made the Model 100/102 popular with journalists in the early 1980s. Tandy RGB11 Computer monitor TRS80 PC - AS IS Fair Condition colour color. You can count Radio Shack and its parent company Tandy among computer companies that failed, but they enjoyed a good run. As hard disk drives at the time of the Tandy 1000's introduction were very expensive, Tandy 1000 systems were not usually equipped with hard drives. £6.47 postage. [4] It also came with the option of integrated disk drives. The RL/HD had a battery-backed real-time clock chip to store date and time information, which the RL lacked. [12] Tandy also regained a significant share of the Apple-dominated educational market,[13] which the two companies had once equally shared. 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. It noted the high level of software compatibility and the good keyboard, and stated that DeskMate was "fairly good ... but a little extra programming work could have turned [it] into a much better program", noting that—for example—the word processor did not have a Move command. [30] The SL came with 384 KB of RAM preinstalled, whereas the SL/2 offered 512 KB. $250.00. Price is US$3200. As it uses a CGA-compatible interface, non-Tandy monitors that support CGA should work. 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. @ Retrobits, my section devoted to the diminutive yet popular 1980s Tandy Pocket Computer line. The Tandy AX was an SX rebadged for sale in Walmart stores. Ending Dec 21 at 9:55AM PST 6d 12h. Many Tandy 1000 enhanced games are featured on YouTube. The SL and TL were also shipped with MS-DOS 3.3 and DeskMate 3 in ROM, and featured a serial EEPROM memory chip to store BIOS settings. Tandy also produced the TRS-80 Color Computer (CoCo), based on the Motorola 6809 processor. [1] However, Tandy later used the TRS-80 name on a number of different computer lines, many of which were technically unrelated to (and incompatible with) the original Model I and its replacements. $600.00. The 1000 EX came with MS-DOS 2.11 and Personal Deskmate on 5.25" 360kB diskettes. Tandy machines were sometimes mocked -- 1980's TRS-80 model was derided as the "Trash-80" by critics -- … Until the 1000 RLX, Tandy 1000s were typically limited to 640 KB main memory, and non-Tandy versions of DOS often reduce the memory available for applications and games. The Tandy 2000 was the company's first computer built around an Intel x86 series microprocessor; previous models were built around the Z80 and 68000 CPUs. The CoCo2 was released in September of 1983. With the exception of the RLX and RSX, the Tandy 1000 machines are XT-class machines, which cannot support extended memory despite some models using 80286 processors. On July 30, 1986, Tandy announced the Color Computer 3. 1983: Tandy releases the TRS-80 Model 2000, which uses the Intel 80186 microprocessor. Tandy (Radio Shack) is a maker of homecomputers between 1977 and early 1990. [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]. Using specially-designed aftermarket cables, it was possible to connect non-Tandy printers to the system. It was more lightweight and came standard with 24K of RAM, expandable to 32K. In addition, the hardware detection routine for the installer of Microsoft MS-DOS 6 could corrupt the serial EEPROM of Tandy 1000 HX machines. The more expensive CM-11 also supported a special proprietary Tandy enhanced 225 scan line text display mode. Early versions of the Model 4 mainboard were designed to accept a Zilog Z800 16 bit CPU upgrade board to replace the Z80 8 bit CPU but this option was never released, as Zilog failed to bring the new CPU to market. Windows 3.xx sound device drivers were available that worked in Windows 95 (with full 9MB RAM) on Tandy 1000 RSX. The catalog number was was 26-3026 for a 16K version with standard Color BASIC and it was listed in Radio Shack catalogs at $239.95 (A 64K CoCo 1, #26-3005, listed for $199). They featured a much more compact case, with at least 512 KB of memory pre-installed, smaller PS/2-style keyboard and mouse ports, and at least one ISA expansion slot. 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. It was possible to use the Model 100 with most phones in the world with the use of an optional acoustic coupler that fit over a standard telephone handset. See more ideas about radio shack, tandy, radio. Furthermore, the Model 4 could be booted with any Model III operating system and emulated the Model III with 100 percent compatibility. TRS-80 was Tandy Corporation's desktop microcomputer model line, sold through Tandy's Radio Shack stores in the late 1970s and early 1980s. Furthermore, as the Tandy 1000's slots were only 10.5" long and are 8-bit only, some units would not fit and/or operate correctly unless they were certified to be Tandy-compatible. Later models of the Tandy 1000 series, such as the 1000 SL, TL and RL series used a keyboard more similar and compatible with the IBM PS/2 series keyboard connector and layout. £53.22. All the ROM programs were written by Microsoft, and even a few of them were written by Bill Gates himself! 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). [11] In 1988 CEO John Roach disagreed with Apple counterpart John Sculley's rejection of the home market: "Let him deny it. Although the Tandy 1000 can run most DOS software, the below programs are known to specifically support Tandy 1000 enhanced features. screen doesnt turn on . Games (792) | Utilities (1) | Educationals (2) Click on the title for more information about that thing. In addition to these, Tandy released a number of computers using the Tandy name itself. Vintage Tandy 1000 HX Personal Computer Model 25-1053 No Monitor Power Tested. A useful feature for the EX and later systems was the ability to boot off either drive, as the drives could be logically swapped when the system booted, so that the drive that was normally drive B: became drive A:, and vice versa, and the drives remained swapped until the system was powered off or reset. It was a full 386-class PC and could run Microsoft Windows 3.x. The SL is the only machine in the line that offers an upper 5.25" bay, and therefore the only model to offer two 5.25" bays, where the other models, including the SL/2 and the entire TL range, feature two upper 3.5" bays and one lower 5.25" bay. Programs loaded using a cassette which worked much better than those for the Sinclair. The floppy drives used jumpers to select the drive number instead of the IBM cable twist. Released in 1983, the Tandy TRS-80 Model 100 was one of the first truly portable computers. This high level of integration made these machines a cost-effective alternative to larger and more complex IBM PC/XT and PC/AT-type systems, which required multiple add-in cards, often purchased separately, to implement a comparable feature-set to the Tandy 1000. Although this arrangement provided a neat physical coupling between the controller and the disk, single-sector internal transfers and dependence on the speed of the host machine to transfer data to memory meant that a trial-and-error approach was still needed to set the disk interleave correctly to ensure optimum transfer rates.
