All the ROM programs were written by Microsoft, and even a few of them were written by Bill Gates (!) Tandy used the main memory for graphics, as a result most programs require 640k or 768k to run. Model 100 woes; 8" drives on Model III? This afforded the user access to popular application software such as MicroPro's Wordstar, Ashton-Tate's dBase II, and Sorcim's Supercalc. The factory hard disk had a capacity on the order of 10 or 20 MB. $250.00. The CoCo2 was released in September of 1983. Tandy 1000 used a proprietary 6-pin female round connector for the joystick port that on the SX/TX was adjacent to the keyboard port in the front of the computer.

Being derived from IBM's PCjr architecture, the Tandy 1000 offered several important features that most IBM PC-compatibles of the time lacked, such as the PCjr's sound generator and extended CGA-compatible graphics controller. [6][8][3] The 1000 has joystick ports like the PCjr, and its 16-color graphics and 3-voice sound, but not the PCjr ROM cartridge ports. $51.00. An external floppy drive could be connected to a port on the back. TRS was formed by the 1963 merger of Tandy Leather Company and Radio Shack (which was almost bankrupt at the time). Pocket! The original Tandy 1000 was a large computer almost the size of the IBM PC, though with a plastic case over an aluminium lower chassis to reduce weight. 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 1000 RSX featured two 16-bit AT ISA slots. 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. 19 watching. 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. Released in 1983, the Tandy TRS-80 Model 100 was one of the first truly portable computers. MS-DOS 2.11, DeskMate 1.0, and a keyboard with the same layout as the Tandy 2000's were included with the computer. [4] It also came with the option of integrated disk drives. 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. The machines could also run 'normal' MS-DOS 3.x, 5.x, and 6.x and Windows 2.x and 3.0 operating systems, although Windows was limited to real-mode operations. The parallel port was bidirectional, a first for the Tandy 1000 series. The Tandy 200 had 24 KB RAM expandable to 72 KB, a flip-up 16 line by 40 column display, and a spreadsheet (Multiplan) included. The RLX is an oddity, as it is an XT-class machine that supports 384 KB of extended memory, and the RSX is a fully AT-class machine which can support up to 9 MB of extended memory. 20 watchers. The RLX had one 1.44 MB 3.5" floppy drive; an empty drive bay could host a second such drive. 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. Radio Shack offered Tandy 1000 PLUS 300-Baud PC Modem that was compatible with the 1000EX/HX that used PLUS slots. £20.92 postage. 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. 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. 2 bids. 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). [32][33], The motherboard had a socket for the 80387SX math coprocessor. 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. 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. 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. Third party modems with speeds of 14k baud should work provided they are 8 bit ISA, and fit. @ Retrobits, my section devoted to the diminutive yet popular 1980s Tandy Pocket Computer line. 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. The Model 100 line also had an optional bar code reader, serial/RS-232 floppy drive and a Cassette interface. Additionally, the installer for MS-DOS 6 could corrupt the contents of the serial EEPROM.[22]. The CoCo3 came with 128K RAM, an analog RGB video port, enhanced 640x192 graphics capability, a 64-color palette and much more. Their own 20 MB hard card was offered for $799, though compatible third-party units were available. $20.00 shipping. 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. As it uses a CGA-compatible interface, non-Tandy monitors that support CGA should work. In addition, the hardware detection routine for the installer of Microsoft MS-DOS 6 could corrupt the serial EEPROM of Tandy 1000 HX machines. 4K of memory, expandable to 16K Expanding the … [12]) It was also marketed as the Micro Executive Workstation (MEWS).[13]. Originally, Tandy offered computers manufactured by Tandon Corporation, and then started producing their own line of systems. Cracking Open the Tandy TRS-80 Model 100. The T-1000 was Tandy’s last attempt in the home computer market. TRS-80 was Tandy Corporation's desktop microcomputer model line, sold through Tandy's Radio Shack stores in the late 1970s and early 1980s. Two major upgrades over the original Tandy 1000 were the inclusion of a DMA controller, which improved the speed of diskette operations and IBM PC-compatibility of these systems, and the addition of two additional ISA expansion slots, to offer a total of five 8-bit ISA slots. While touted as being compatible with the IBM XT , the Tandy 2000 was different enough that most existing PC software that was not purely text-oriented failed to work properly. This machine was clearly aimed at the home market, where the Model II and above were sold as business machines. The original 1000 and SX had a light-pen port. The RL/HD had a battery-backed real-time clock chip to store date and time information, which the RL lacked. Two sockets for SIMM memory cards were provided. The Tandy 1000 SX used a 7.16 MHz 8088-2 processor, had 384k of memory (upgradeable to 640 KB on the motherboard), came with either one or two 5.25" internal floppy disk drives, and had the light pen port (not a serial port) like the original Tandy 1000. Tandy! See Photos. It also offered multiple built-in I/O ports, including a joystick port which was frequently a separate add-on card on non-Tandy machines. On July 30, 1986, Tandy announced the Color Computer 3. Radio Shack sold the Tandy DMP-130A dot matrix printers to go along with their Tandy 1000 line, along with compatible card-edged printer cable. View and Download Tandy TRS-80 Model 16 service manual online. 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. 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. As margins decreased in PC clones, Tandy was unable to compete and stopped manufacturing their own systems, instead selling computers manufactured by a variety of companies, AST Research and Gateway 2000 among them. Tandy Laptop Computer, Model 200, 1985 Add to Set Contact us About this Share Summary. Help support the museum by buying from the museum shop. 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. With its graphics, sound, and built-in joystick ports, the 1000 was the best computer for PC games until VGA graphics became popular in the 1990s. 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. 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. It features Z80A and 68000 processors, 512 KB RAM, … 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. The enhanced graphics and sound often tax the processor, so an 80286 processor or faster is recommended for best results. OS-9, a multitasking, multi-user operating system was supplied for this machine. OS-9, a multitasking, multi-user operating system was supplied for this machine. The memory size was 640 KB, with sockets for an additional 128 KB devoted to the onboard video logic. [citation needed] A magazine was published which offered programs for both the CoCo and MC-10 but very few programs were available for purchase. This early consumer PC gained its name from a combination of the store name with that of its parent company, Tandy, resulting in "Tandy/RadioShack" or TRS. Tandy advertised the Model II as "a business computer — not a hobby, 'home' or personal computer". As a result, fitting a hard drive to an SL that already has the upper and lower 5.25" bays populated may require either the removal of one of the devices in those bays, or the installation of a hard disk card-style bracket which seats in one of the ISA slots. [3], Released in November 1984,[1] the $1,200 Tandy 1000 offered the same functionality as the PCjr, but with an improved keyboard and better expandability and compatibility. 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. Major software publishers and makers of game and educational software, such as Sierra and Broderbund, offered software titles that specifically supported Tandy's unique and proprietary 16-color graphics, 3-voice sound, and other Tandy specific hardware features. 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. 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 16B was the most popular Unix computer in 1984, with almost 40,000 units sold.[11]. 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. For the Casio users, Tandy chose three units from the Casio stable,calling them the Pocket Scientific Computers and emphasizing theiradditional specialized mathematic functions. The case was a bit smaller than the original CoCo, very similar to the TDP-100. These programs require DOS to run. The most current version of MS-DOS for Tandy 1000 is DOS 3.22. 26.3002; Super VGA with the Tandy 1000 RLX; Trs-80 Model 4p 80x24 screen issues (gate array motherboard) TRS-80 Model II acquired. 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. RARE Vintage Tandy 128k Color Computer 3 NOS NEW OLD STOCK with Games NO RESERVE Although the Tandy 1000 can run most DOS software, the below programs are known to specifically support Tandy 1000 enhanced features. All Tandy 1000 computers featured built-in video hardware, enhanced sound hardware (based on one of several variants of the Texas Instruments SN76496 sound generator) and numerous peripheral interfaces, including game ports compatible with those on the TRS-80 Color Computer, an IBM-standard floppy-disk controller supporting two drives, and a parallel printer port, all integrated into the motherboard in addition to the hardware standard on the IBM PC/XT and, in later Tandy 1000 models, PC/AT motherboards. [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". Tandy Radio Shack TRS-80 Manuals. Jan 28, 2019 - The Tandy Color Computer. Tandy offered 2 color monitors specific for its Tandy 1000 computers: the CM-5, with a 0.64 millimeter dot pitch,[24] and the Tandy CM-11 with a dot pitch of 0.42 mm. 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. The external drive was the standard 360 KB 5.25 inch format; in 1988 a compatible 720 KB 3.5 inch model was offered. The PLUS connector was designed for compactness in these models with built-in keyboards. The hard disk RLX/HD came with a 20 MB hard disk and 1 MB RAM preinstalled. Other PLUS cards could be installed to add serial ports, a 1200-baud modem, a clock/calendar and bus mouse board, or a proprietary Tandy network interface. Tandy 1000 EX and Tandy 1000 HX). $899.00. Tandy 1000TX and beyond used a proprietary floppy drive cable port, that also powered the floppy drive. 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 Model 100 had an internal 300 baud modem, built-in BASIC, and a limited text editor. May 28, 2019 - The fruits of Radio Shack's digital loins. [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". Opening the cover requires some care, but once inside, it's easy to work on. 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. There was, however, a quirk in the DOS 4.0 environment that prevented that version of DOS from working with Tandy 1000 HX computers. It was announced in May 1979, deliveries began in October, and only Tandy-owned RadioShack stores sold the computer. Another improvement over the EX is the addition of a serial EEPROM to store configuration information, enabling similar functionality to today's CMOS NVRAMs. 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. Examples of such software includes Mario's Typing Tutor, Star Trek, Freddy Pharkas: Frontier Pharmacist, Sargon Chess. The EX and, later, the HX would be among the most popular of the Tandy 1000 line because of their (relatively) low price. [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. $15.00 + shipping . 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]. 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". 53-key professional keyboard 6. It's first computer, the TRS-80, was the best selling computer until 1980. This was somewhat mitigated by the availability of the CP/M from third parties. thank you Tandy also produced the TRS-80 Color Computer (CoCo), based on the Motorola 6809 processor. 1983: Tandy releases the TRS-80 Model 2000, which uses the Intel 80186 microprocessor. The machine itself supplied power to the external drive, so only Tandy's unit was usable with the EX and HX. They were lower profile than typical modern PC keyboards and the keys were recessed in the center, giving them a "melted" look. Some DOS games do not work with these joystick ports, but those that support Tandy 1000 graphics and sound work. Furthermore, the Model 4 could be booted with any Model III operating system and emulated the Model III with 100 percent compatibility. The first of these was the Tandy 2000, followed later by the less expensive Tandy 1000. The original Tandy 1000 (and many other models), like most home computers sold at the time, did not have a hard disk drive. Manufacturer : Radio Shack - Tandy Type : Computer The rear model identification sticker mentioned Tandy but not Radio Shack, perhaps due to the issues with the AX. 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. Its keyboard had three function keys and a control key. Games (792) | Utilities (1) | Educationals (2) Click on the title for more information about that thing.

The Tandy Color Computer 3 is the most desirable of the Color Computer line because it’s the most versatile. 1983: Radio Shack unveils the TRS-80 Model 12 at the CP/M '83 Show. However, these were incompatible with common AT IDE hard drives. The Tandy 100 was actually a computer made in Japan by Kyocera. [8], BYTE called the 1000 "a good, reasonably priced IBM PC clone that has most of the best features of the IBM PC and PCjr ... at current prices it is a very good alternative". The Model 100 was designed by the Japanese company Kyocera with software written by Microsoft. 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. It was also marketed to home users and businesses interested in both MS DOS and Apple II compatibility. Most of the desktop-type Tandy 1000 units could accept regular 8-bit ISA bus MFM, RLL and SCSI controllers like typical XT-class machines; however, care had to be taken when configuring the cards so that they did not cause conflicts with the on-board Tandy-designed peripherals. A more modern version of Microsoft's BASIC interpreter more closely resembled the MS-DOS GW-BASIC, featuring PC-like functionality. It is sure to put a whopping dent not only into PCjr sales, but into sales of the PC 'senior' as well". Unlike most PC clones, several Tandy 1000 computers had MS-DOS built into ROM and could boot in a few seconds. $90.92 shipping. 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. A later revision of the original Tandy 1000 model was the Tandy 1000A.
