It was also marketed to home users and businesses interested in both MS DOS and Apple II compatibility. The hard disk occupied the empty drive bay, so this version supported only a single floppy drive. (The Model 100 firmware was the last Microsoft product to which Bill Gates was a major code contributor. In addition to these, Tandy released a number of computers using the Tandy name itself. 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. With two 4 MB SIMMs installed, the 1000 RSX could be expanded to 9 MB RAM (without using an ISA slot). In this video I show the 102 connected to the Tandy CCR-81 cassette recorder. Tandy introduced three other models in this line: the Model 200, Model 600, and Model 102. Cd Rom Recommendation for a Tandy 3100 Model 10 (486sx) The Tandy 1000 TL and QRAM; This Week In TRS-80: Episode 5 (20th December, 2018) TRS-80 Trash Talk - Episode 27 - The First Tandy Computers; Tandy 5000 - Radio Shack Product Announcement - April 21, 1988; eBay: Vintage Radio Shack TRS-80 Model 1 Computer - Catalog # 26-1001 First Cat #! 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. 1983: Tandy releases the TRS-80 Model 2000, which uses the Intel 80186 microprocessor. Tandy ... TRS-80 Model 100 Portable Computer. Tandy (Radio Shack) is a maker of homecomputers between 1977 and early 1990. Both machines could be expanded to 640 KB, although the graphics controller reserved a portion of this memory, yielding only 608 KB available the operating system, even on systems using add-in ISA graphic cards. 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. This machine was clearly aimed at the home market, where the Model II and above were sold as business machines. The Tandy 1000 SL and SL/2 feature an Intel 8086 processor running at 8 MHz. In February 1982, Tandy released the TRS-80 Model 16,[8] as the follow-on to the Model II; an upgrade kit was available for Model II systems. The TRS-80 launched in 1977, before the home computer market had really exploded. The CoCo3 came with 128K RAM, an analog RGB video port, enhanced 640x192 graphics capability, a 64-color palette and much more. One option for contemporary users of these systems would be to install and use XT ISA CompactFlash adapters; this is also the most practical way to install a hard drive into a Tandy 1000 EX or HX, using an adapter cable that adapts the male PLUS-style connector to an 8-bit ISA card-edge slot. [8], The Model 16 evolved into the Model 16B with 256 KB in July 1983,[10] and later the Tandy 6000, gaining an internal hard drive along the way and switching to an 8 MHz 68000. Tandy also offered monochrome monitors that support MDA and Hercules standard that also work with Tandy 1000. Pocket! The memory size was 640 KB, with sockets for an additional 128 KB devoted to the onboard video logic. They were lower profile than typical modern PC keyboards and the keys were recessed in the center, giving them a "melted" look. The DAC could be used to emulate the Covox Speech Thing via MS-DOS device drivers for limited sound support. Unlike the 2000 it would be PC compatible with the IBM PC, and support the PCjr graphics standard. @ Retrobits, my section devoted to the diminutive yet popular 1980s Tandy Pocket Computer line. Manufacturer : Radio Shack - Tandy Type : Computer Also available as an option to the Model 100 was an external expansion unit supporting video and a 5​1⁄4" disk drive, connected via the 40-pin expansion port in the bottom of the unit. With the exception of the 1000 EX and HX, Tandy used industry standard 8-bit XT ISA slots in their desktop models, including the SX, TX, SL, and TL series, but the actual length was limited to 10.5 inches or shorter, rather than the industry standard XT length of 13 inches. The RL/HD came with a 20MB drive preinstalled. Tandy Corporation released several computer product lines starting in 1977, under both TRS-80 and Tandy branding.. TRS-80 was a brand associated with several desktop microcomputer lines sold by Tandy Corporation through their Radio Shack stores. The Tandy 1000 TX was similar to the 1000 SX with its detached keyboard, unique parallel port edge connector and XT-style architecture in a slightly modified case. 6 Disks of Games for the Radio Shack TRS-80 Model I vintage computer. Early Tandy 1000 models used a non-standard card-edge parallel printer port rather than industry standard DB-25 printer port. Watch. It is sure to put a whopping dent not only into PCjr sales, but into sales of the PC 'senior' as well". Radio Shack released one of the first home computers, the TRS-80 Model I, in 1977. It required a Tandy 1000 compatible floppy drive, though it may be possible to modify a floppy drive cable to make a standard floppy drive work. 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. It required a Tandy-1000 compatible printer cable to connect to a standard printer parallel port. The enhanced graphics and sound often tax the processor, so an 80286 processor or faster is recommended for best results. However, around the time of its introduction, the industry began moving away from MS-DOS compatible computers and towards fully IBM PC compatible clones; later Tandy offerings moved toward full PC hardware compatibility. Also known as the "CoCo"!. Unlike the SL series machines, the TL machines came with the SmartWatch real-time clock logic built-in, which was powered by a removable 3-volt CR2032 button-cell battery on the motherboard. The RL-series and RSX include provisions for an internal hard disk drive, depending on the model: the RL-series featured a built-in XT-IDE hard drive interface, while the RSX featured an AT-compatible IDE interface. Tandy's first design for the business market was a desk-based computer known as the Tandy 10 Business Computer System, which was released in 1978 but quickly discontinued. This is socketed, and thus upgradeable with an NEC V30. The initial price was $599.95, which included a typewriter-style (not membrane) keyboard, monitor, and cassette recorder. The MC-10 was a short-lived and little-known Tandy computer, similar in appearance to the Sinclair ZX81. The EX and HX are upgradable via Tandy PLUS cards, and these systems have bays for three cards. This was later changed to a standard DB-25 connector on the 1000 RL. The EX and HX utilized a PLUS-style connector, which was electronically identical to an 8-bit XT ISA slot, but had a 62-pin Berg connector instead of a card edge, rendering it incompatible with ISA cards without an adapter. By putting the basic elements of DOS and Deskmate in ROM and eliminating the memory test on startup, the HX booted quickly compared to other contemporary MS-DOS machines, despite having no immediate provisions for a hard disk drive. It was not an upgrade of the Model I, but an entirely different system with state-of-the-art hardware and numerous features not found in the primitive Model I. In July 1980 Tandy released the Model III, a mostly-compatible replacement for the Model I. In addition to Tandy MS-DOS 2.11R, the HX shipped with Personal Deskmate 2. [2] While preparing the Tandy 2000—the company's first MS-DOS computer—for release in November 1983, Tandy began designing the Tandy 1000, code named "August". The Tandy 1000 RL/RLX/RSX series were slim-line desktop home computers. The Tandy Color Computer 3 is the most desirable of the Color Computer line because it’s the most versatile. 1983: Radio Shack introduces the TRS-80 Pocket Computer, Model PC-4, replacing the PC-1, for US$70. The 16B was the most popular Unix computer in 1984, with almost 40,000 units sold.[11]. [4][5][6] "How could IBM have made that mistake with the PCjr?" The TLs had 640 KB of memory preinstalled, with an option for an extra 128 KB for video frame buffering just as in the 1000 TX. They were lightweight, rugged, and had rechargeable, efficient batteries. The factory hard disk had a capacity on the order of 10 or 20 MB. Starting with the Tandy 1000 TL/2, XT IDE controllers were integrated onto the motherboard. This extra 128 KB could only be used for and by the on-board video controller, so it was impractical to expand the on-board memory beyond 640 KB if a VGA graphics card was installed. The Tandy AX was an SX rebadged for sale in Walmart stores. or Best Offer. It competed directly with the Commodore 64, Apple II, and Atari 8-bit family of computers. [9], Although Tandy initially marketed the 1000 as a business computer like the IBM PC, InfoWorld stated in 1985 that the company "produced a real home computer". Radio Shack also offered 2400-baud internal modem. A 16 KB RAM expansion pack that connected on the back of the unit was offered as an option as was a thermal paper printer. The magazine also mentioned the computer's short slots. A Color Computer 1 is arguably the second most valuable because it was the first. The Model 4's new hardware features included a larger display screen with 80 columns by 24 rows, inverse video, and an internal audio speaker. The Model 4 could run the industry-standard CP/M operating system without hardware modification (as was needed for the Model III). A look at the final member of the Radio Shack TRS-80 series of computers, the Tandy Model 4D, sold from 1985 until at least 1990 (possibly even later). This printer was sold at home budget prices. 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 original Tandy 1000 (and many other models), like most home computers sold at the time, did not have a hard disk drive. [18], In an article subtitled "Junior meets his match", John J. Anderson of Creative Computing called the original Tandy 1000 "the machine IBM was too inept, incapable, or afraid to manufacture. screen doesnt turn on . Common models of the machine included the Tandy 1000, 1000 EX, 1000 HX, 1000 SX, 1000 TX, 1000 SL, 1000 RL, and 1000 TL. There are 531 known programs for the Tandy Color Computer, divided as follows:. Although less popular than the Model 100, the Tandy 200 was also particularly popular with journalists in the late 1980s and early 1990s. A more modern version of Microsoft's BASIC interpreter more closely resembled the MS-DOS GW-BASIC, featuring PC-like functionality. The TL series offered two upper 3.5" bays and one lower 5.25" bay. Vintage Tandy 1000 HX CM-5 Personal Computer & Radio Shack Color Mouse Lot. The Tandy 1000 EX and HX were designed as entry-level IBM-compatible personal computers, and marketed as starter systems for people new to computing. The RSX, however, incorporated the AT keyboard protocol, making it the first 1000-series system to offer more complete compatibility with typical PS/2 keyboards, and AT keyboards using an adapter. or Best Offer. The rear model identification sticker mentioned Tandy but not Radio Shack, perhaps due to the issues with the AX. Tez reference Time article on first Tandy computer – TRS-80 ! 1983: Radio Shack unveils the TRS-80 Model 12 at the CP/M '83 Show. MS-DOS 2.11, DeskMate 1.0, and a keyboard with the same layout as the Tandy 2000's were included with the computer. 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). The keyboard was much better than the original CoCo "chicklet" keyboard. Price is US$3200. The TRS‑80 Model I had very impressive specifications for a $399.95 computer in 1977: 1. a Zilog Z80 processor running at 1.77 MHz 2. a monochrome, uppercase-only text display, with either 64 columns by 16 rows or 32 columns by 16 rows 3. 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. These were manufactured by Sharp or Casio, depending on the model. $85.00 shipping. The Tandy 1000 EX featured a 5.25" floppy drive built into the right-hand side of computer casing. The graphics controller now supported 640 × 200 × 16 resolution as well as a Hercules Graphics Card-compatible, 720 × 350 mode for monochrome monitors. Tandy Color Computers. $899.00. 1983: Radio Shack unveils the TRS-80 Model 12 at the CP/M '83 Show. It used an all-new operating system derived from the advanced Model III LDOS 5, licensed from Logical Systems, now christened TRSDOS Version 6. While many 8-bit cards met this length requirement, some cards such as hard cards, EMS memory cards, and multifunction cards that required the standard 13" length did not fit in the 1000's case. Funky serial on a Model II; Parking a hard card; Tandy SL monitor questions. RARE VINTAGE RADIO SHACK/TANDY TRS-80 PORTABLE COMPUTER MODEL 4P AS-IS FOR PARTS. There may be compatibility issues with later versions of DOS such as DOS 5 and DOS 6.

The Model I included a full-stroke QWERTY keyboard, floating-point BASIC, a monitor, and a starting price of US$600. In the early 1980s, Tandy began producing a line of computers that were "DOS compatible": able to run MS-DOS and certain applications, but not fully compatible with every nuance of the original IBM PC systems. Games (792) | Utilities (1) | Educationals (2) Click on the title for more information about that thing. Radio Shack offered one button joystick that worked with its proprietary 6-pin DIN joystick connector that was compatible with the older TRS-80 Color Computer but not standard 15-pin IBM PC game ports often found on sound cards and i/o multifunction ISA cards. Yes, there are quite a few Pocket Computer sites out there, but most of them cover the Casio and Sharp models that Tandy cloned and merely add the Tandy variants as a footnote or label variation. May 28, 2019 - The fruits of Radio Shack's digital loins. However, these were incompatible with common AT IDE hard drives. 1985: March - Radio Shack introduces the Tandy 6000 multiuser system. Tandy 1000 EX and Tandy 1000 HX). Part two of my videos on my 1980's Tandy Model 102 computer. thank you He favorably mentioned its low price, good PC-software compatibility, and bundled DeskMate ("you might never need another software package for your computer"). The magazine called the 1000 "almost as fully IBM PC compatible as a computer can get", but gave DeskMate a mixed review and advised customers of the computer's inability to use full-length PC expansion cards. The boot disk has both DOS and Apple software and is copy-protected. This was to permit the installation of an upgraded graphics card, typically an EGA or VGA card, in an expansion slot. Using specially-designed aftermarket cables, it was possible to connect non-Tandy printers to the system. The Model 100 had an internal 300 baud modem, built-in BASIC, and a limited text editor. The front of the case was beveled differently from the Radio Shack machines, but the button, port and slot placements were the same, except for the power button's shape. 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. or Best Offer. He's the only other person that's well-represented in the home market, and if he wants to abandon it, it's all right with me". Topics: TRS-80, Radio Shack, Computers. A newer version of the TRS–80 (popular models now cost $999) has become the largest-selling computer of all time, and Tandy now commands 40% of the small-computer market. The successor to the Model III was the Model 4. It came standard with one internal 5.25" double-density floppy disk drive, with an additional exposed internal bay usable for the installation of a second 5.25" disk drive (available as a kit from Radio Shack). You can count Radio Shack and its parent company Tandy among computer companies that failed, but they enjoyed a good run. £26.63. 1985: March - … It also had Tandy MS-DOS 2.11R in ROM, which could be accessed by starting the computer with no bootable disk present. Tandy 1000 EX Personal Computer. 1983: Tandy releases the TRS-80 Model 2000, which uses the Intel 80186 microprocessor. The EX and, later, the HX would be among the most popular of the Tandy 1000 line because of their (relatively) low price. Only 1 MB or 4 MB SIMMs of the 9-chip type were supported, and if two were installed they had to be of like capacity. The 1000 RSX featured two 16-bit AT ISA slots. Early Tandy 1000 models used Phoenix BIOS. Common models of the machine included the Tandy 1000, EX, HX, SX, TX, SL, SL/2, RL, and TL, TL/2, TL/3. The Tandy 100 was actually a computer made in Japan by Kyocera. 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]. See Photos. The original 1000 and SX had a light-pen port. See more ideas about radio shack, tandy, radio. 19 watching. [9] In early 1983, Tandy switched from TRSDOS-16 to Xenix. C $576.71. Tandy machines were sometimes mocked -- 1980's TRS-80 model was derided as the "Trash-80" by critics -- … Both the TRS-80 and Tandy brands were used for a range of "Pocket Computers" sold by Tandy. 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. [8] The company claimed that the 1000 was "the first fully IBM PC-compatible computer available for less than $1000". 20 watchers. Between 1977 and 1979, it sold 100,000 units. Vintage Radio Shack TR-80 Pocket Computer, Model PC-3, Cat. Although the Tandy 1000 can run most DOS software, the below programs are known to specifically support Tandy 1000 enhanced features. Furthermore, the Model 4 could be booted with any Model III operating system and emulated the Model III with 100 percent compatibility. Although the press saw the 1000 as former personal-computer leader Tandy admitting that it could no longer focus on proprietary products in a market the IBM PC dominated, the 1000 sold more units in the first month than any other Tandy product and by early 1985 was its best-selling computer. The PCjr's enhanced graphics and sound standards became known as "Tandy-compatible". [2], By 1979, the TRS-80 had the largest selection of software in the microcomputer market. The external drive was the standard 360 KB 5.25 inch format; in 1988 a compatible 720 KB 3.5 inch model was offered. Radio Shack/Tandy TRS-80 Portable Computer MODEL 4P RARE! Most versions of MS-DOS worked with the 1000 HX, including DOS 3.x, and some later versions. An adjustable potentiometer inside the system controlled the volume of the internal speaker. Tandy! However, it was not a full AT-class machine, as it still had an 8-bit ISA bus (as with the RL, one half-size expansion slot) and only 8 IRQs and 4 DMA channels. In October 1979 Tandy began shipping the TRS-80 Model II, which was targeted to the small-business market. The Tandy 1000 - The best MS-DOS computer in 1984. 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). Programs for the MC-10 were not compatible with the CoCo. All the ROM programs were written by Microsoft, and even a few of them were written by Bill Gates himself! Tandy 1000 computers were some of the first IBM PC clones to incorporate a complete set of basic peripherals on the motherboard using proprietary ASICs, the forerunner of the chipset. The 1000 SX came with MS-DOS 3.2 and Deskmate II on 5.25" 360kB diskettes. 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 1000 EX came with MS-DOS 2.11 and Personal Deskmate on 5.25" 360kB diskettes. Its microprocessor was a faster Z80A 4 MHz CPU. £6.47 postage. Tandy also produced the TRS-80 Color Computer (CoCo), based on the Motorola 6809 processor. 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]. This was essentially a Model 16B (described below) without the Motorola processor, and could be upgraded to a Model 16B. Third party modems with speeds of 14k baud should work provided they are 8 bit ISA, and fit. 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. Win, Lose Or Draw PC IBM TANDY APPLE II COMMODORE 64 5.25. 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. By 1993, changes in the market made it increasingly difficult for Tandy Corporation to make a profit on its computer line. A cat resting on a Tandy 1000 EX computer, replacing the light pen port of previous models. A more upscale offering, the RSX offered a 25 MHz 80386SX processor, 1 MB RAM, two 16-bit ISA slots, AcuMos SVGA video, a bidirectional parallel port, and standard PS/2 keyboard and mouse ports. The Tandy 2000 system was similar to the Texas Instruments Professional Computer in that it offered better graphics, a faster processor (80186) and higher capacity disk drives (80 track double sided 800k 5.25 drives) than the original IBM PC. Price is US$3200. an amazed Tandy executive said regarding its chiclet keyboard,[7] and another claimed that the 1000 "is what the PCjr should have been". 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. Its keyboard had three function keys and a control key. sale is final no return accepted . Many Tandy 1000s sold to schools came with the Diamond Trackstar 128 installed,[26] and home owners also purchased this for compatibility with both DOS and Apple II software.[27]. Free shipping. The Tandy 1000 TL and TL/2 used 8 MHz Intel 80286 processors, whereas the TL/3 used a 10 MHz 80286. Their own 20 MB hard card was offered for $799, though compatible third-party units were available. TRS-80 was Tandy Corporation's desktop microcomputer model line, sold through Tandy's Radio Shack stores in the late 1970s and early 1980s. Tandy 1000s came shipped with one of several varieties of Deskmate, their own GUI productivity software suite. The most current version of MS-DOS for Tandy 1000 is DOS 3.22. Alternatively, list the games for a different machine. It concluded that "By making the 1000 inexpensive and adaptable" and including DeskMate, "Tandy produced a real home computer". The Model 16 sold poorly at first and was reliant on existing Model II software early on. The TL/2, TL/3, RL and RLX all used the XT IDE interface, where the later (and significantly upgraded) RSX was the first and only Tandy 1000 model computer to use a standard AT IDE interface. 128 KB of memory was standard, with the computer accepting up to 640 KB of total memory with the addition of expansion cards. A jumper on the board allowed the user to change the microphone input to a line-level output. In addition to offering redesigned cases, the machines offered a more integrated motherboard with improved graphics and sound capabilities while dropping composite video output. [30] The SL came with 384 KB of RAM preinstalled, whereas the SL/2 offered 512 KB. By the mid-80's, it became obvious that the CoCo was lagging behind the competition. The Tandy Digi-Mouse was also available, which required a separate controller that was available in either ISA or PLUS format. There are also games and educational software that supports second generation Tandy 1000 graphics and sound, which offers 640 by 200 by 16 colors, and 8-bit DACs, found only on the 1000 sl/tl series. It was announced in May 1979, deliveries began in October, and only Tandy-owned RadioShack stores sold the computer. [10] The 1000 helped the company obtain a 9.5% share of the US home-computer market in 1986, a year in which Tandy stated that half of its compatibles were purchased for the home. 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). Tandy offered its first model with 4K of RAM, a 1.77 MHz processor and a 12-inch monitor for $600. [12]) It was also marketed as the Micro Executive Workstation (MEWS).[13]. [19], InfoWorld noted the 1000's low price ("fully one-third less than a comparably equipped IBM PC"), predicted that the computer was really intended for "the elusive home computer market", and speculated that "in retrospect it might have been the PCjr's final straw". Software that supported Tandy's graphics were typically labelled on the package as Tandy 1000/PCjr compatible. Tandy Computer TRS 80 - Model 40. The market is big". If you are looking for books, expansions or just a more visual representation of this data, you can generate a "wall" to your exact requirements. An external floppy drive could be connected to a port on the back. See more ideas about tandy, computer, old computers. or Best Offer. $119.99. 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. Two sockets for SIMM memory cards were provided. The Tandy 1000 Professsional Computer was the first in a line of more or less IBM PC compatible home computer systems produced by the Tandy Corporation for sale in its Radio Shack chain of stores. The Tandy 1000 SX and TX were upgraded versions of the original Tandy 1000, utilizing a similar chassis. Tandy Graphics or TGA) and three-voice sound hardware of the Tandy 1000. hello all; Vswitch on a 1000TX. However, it was possible to add a hard drive to most Tandy 1000 computers. The TRS-80 Model 200 was among the first generation of notebook-style computers. M a n i a! Originally, Tandy offered computers manufactured by Tandon Corporation, and then started producing their own line of systems. The 200 and 600 had enhanced displays and keyboards, at the expense of being less compact. 1983: Radio Shack unveils the TRS-80 Model 12 at the CP/M '83 Show.
