Third party modems with speeds of 14k baud should work provided they are 8 bit ISA, and fit. This machine was clearly aimed at the home market, where the Model II and above were sold as business machines. From United States. The circuit … Released in 1983, the Tandy TRS-80 Model 100 was one of the first truly portable computers. In addition to these, Tandy released a number of computers using the Tandy name itself. 1983: Radio Shack unveils the TRS-80 Model 12 at the CP/M '83 Show. Tandy introduced three other models in this line: the Model 200, Model 600, and Model 102. In addition to offering redesigned cases, the machines offered a more integrated motherboard with improved graphics and sound capabilities while dropping composite video output. They dealt in many different electronic products, but introduced two computers that were important in fostering the personal computer revolution. TRS was formed by the 1963 merger of Tandy Leather Company and Radio Shack (which was almost bankrupt at the time). The TRS-80 launched in 1977, before the home computer market had really exploded. 1983: Radio Shack introduces the TRS-80 Pocket Computer, Model PC-4, replacing the PC-1, for US$70. 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. 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. Discussion for Tandy computers, including the TRS-80 Models I, II, III, and 4, Color Computers, and Model 100. The 1000 RSX featured two 16-bit AT ISA slots.

This printer was sold at home budget prices. Its microprocessor was a faster Z80A 4 MHz CPU. $899.00. The rear panel had the same ports as the 1000 SX, except that an RS-232C serial port replaced the light-pen port. 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. 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. 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. 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. Tandy shipped its own version of DOS. English: Category for the original "TRS-80 Micro Computer System" (AKA Model I) and its compatible successors, the Model III and Model 4 TRS-80 microcomputer launched in 1977, sold by Tandy Corporation through RadioShack stores The Model II was replaced in 1982 by the TRS-80 Model 12. $85.48 shipping. 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 Tandy 1000 SX and TX were upgraded versions of the original Tandy 1000, utilizing a similar chassis. 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 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. 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 case was a bit smaller than the original CoCo, very similar to the TDP-100. Many Tandy 1000 enhanced games are featured on YouTube. The RLX had one 1.44 MB 3.5" floppy drive; an empty drive bay could host a second such drive. (The Model 100 firmware was the last Microsoft product to which Bill Gates was a major code contributor. This machine was clearly aimed at the home market, where the Model II and above were sold as business machines. 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 board has a pass-through RGB cable and floppy drive cable, and required an open 10 inch 8-bit ISA slot, and used a boot disk to boot into Apple mode. By 1993, changes in the market made it increasingly difficult for Tandy Corporation to make a profit on its computer line. It made computer history as one of the first mass marketed, fully assembled microcomputers. (All ports contained on the CoCo 1 and 2 models were also available on the CoCo3, e.g. TURNS ON WITH DISK.

C $576.71. thank you The MC-10 was a short-lived and little-known Tandy computer, similar in appearance to the Sinclair ZX81. 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 used an all-new operating system derived from the advanced Model III LDOS 5, licensed from Logical Systems, now christened TRSDOS Version 6. [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". Watch. They were lower profile than typical modern PC keyboards and the keys were recessed in the center, giving them a "melted" look. $85.00 shipping. [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. 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. Q P S p o A 8 G n s o r I J F e d 1 U K. RADIO SHACK TANDY TRS-80 PORTABLE COMPUTER MODEL 4P - Untested Past Powering On.

The Tandy 200 was introduced in 1984 as a higher-end complement to the Model 100. 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. Prices started from $999 for the diskless version. Price is US$3200. Because of the slimline case, only one hard drive could be installed alongside the 1.44 MB 3.5" floppy drive. Sleek andimpressive units on the outside with a generous 24-character LCD inside,they were nevertheless plagued by poor build qualit… A Color Computer 1 is arguably the second most valuable because it was the first. Also known as the "CoCo"!. As the Tandy 1000 used the same game ports as the Tandy Color Computer series, the 26-3025 Color Mouse and 26-3125 Deluxe Mouse were compatible with the Tandy 1000, though not all DOS software and drivers were written to recognize them. The computer was too limited for such use, so the company began development on the Model II in late 1978. High detailed 3D model of Tandy 1000 personal computer from 80th. TRS-80 was Tandy Corporation's desktop microcomputer model line, sold through Tandy's Radio Shack stores in the late 1970s and early 1980s.

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. The Tandy SL and TL series of computers were updates of the SX and TX, respectively. 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. [4] 80 Micro approved of the 1000's PC compatibility and stated that the exterior design "gives it a feeling of quality and confidence". TRS-80 Microcomputer System Model I (26-1003) 1977 The TRS-80 Model I, or just TRS-80 Microcomputer System as shown on the computer itself, was introduced in August 1977. The Model I included a full-stroke QWERTY keyboard, floating-point BASIC, a monitor, and a starting price of US$600. $90.92 shipping. You can count Radio Shack and its parent company Tandy among computer companies that failed, but they enjoyed a good run. 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]. 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]. Although the original Tandy 1000 came in an IBM PC-like desktop case, some models, notably the 1000 EX and 1000 HX, used home-computer-style cases with the keyboard, motherboard and disk drives in one enclosure.

Unlike most PC clones, several Tandy 1000 computers had MS-DOS built into ROM and could boot in a few seconds. 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. 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. Tandy Radio Shack wanted to compete in the education, school and home market, which was dominated at the time by the Apple IIe. Vintage Tandy Computer Cassette Recorder CCR-81 Model 26-1208A 2 Mic Radio Shack. [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. Between 1977 and 1979, it sold 100,000 units. 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. [30] The SL came with 384 KB of RAM preinstalled, whereas the SL/2 offered 512 KB. 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. The DAC could be used to emulate the Covox Speech Thing via MS-DOS device drivers for limited sound support. 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]. 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 later Tandy 1000 systems and follow-ons were also marketed by DEC, as Tandy and DEC had a joint manufacturing agreement. Manufacturer : Radio Shack - Tandy Type : Computer 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. 1985: March - Radio Shack introduces the Tandy 6000 multiuser system. shipping: + $12.00 shipping . The TRS-80 Model 200 was among the first generation of notebook-style computers. These were manufactured by Sharp or Casio, depending on the model. With the introduction of the Model III, Model I production was discontinued as it did not comply with new FCC regulations as of January 1, 1981 regarding electromagnetic interference.[4][5][6]. The “T-1000” was a workhorse in the IBM PC world, large numbers of units are still in active service today as it’s construction was quite robust. 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. The PCjr's enhanced graphics and sound standards became known as "Tandy-compatible". 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. The Model III could run about 80% of Model I software, but used an incompatible disk format. 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. 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. 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. 1983: Radio Shack introduces the TRS-80 Pocket Computer, Model PC-4, replacing the PC-1, for US$70. 2 bids. Examples of such software includes Mario's Typing Tutor, Star Trek, Freddy Pharkas: Frontier Pharmacist, Sargon Chess. The Tandy 200 also included DTMF tone-dialing for the internal modem. ...

[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. The memory size was 640 KB, with sockets for an additional 128 KB devoted to the onboard video logic. Tandy bundled DeskMate, a graphical suite of consumer-oriented applications, with various Tandy 1000 models. It worked with many games written to take advantage of Tandy graphics and sound. hello all; Vswitch on a 1000TX. 1985: March - Radio Shack introduces the Tandy 6000 multiuser system. 1983: Tandy releases the TRS-80 Model 2000, which uses the Intel 80186 microprocessor. Help support the museum by buying from the museum shop. This was essentially a Model 16B (described below) without the Motorola processor, and could be upgraded to a Model 16B. They were offered in a compact, all-in-one chassis that featured a 7.16 MHz 8088 (capable of clocking down to 4.77 MHz), 256 KB of memory (expandable to 640 KB with a PLUS memory expansion board), PCjr- and CGA-compatible Tandy Video graphics controller, a keyboard and, depending on the model, either a single 5.25" 360 KB floppy drive, or one to two 3.5" 720 KB floppy drives. The hard disk RLX/HD came with a 20 MB hard disk and 1 MB RAM preinstalled. 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 Tandy 1000 EX and HX were designed as entry-level IBM-compatible personal computers, and marketed as starter systems for people new to computing. As it uses a CGA-compatible interface, non-Tandy monitors that support CGA should work. Windows 3.xx sound device drivers were available that worked in Windows 95 (with full 9MB RAM) on Tandy 1000 RSX. The hard disk occupied the empty drive bay, so this version supported only a single floppy drive. The TL/3 also offered a high-density floppy drive controller for 1.44 MB drives, though it shipped with a double-density 3.5" 720 KB drive. 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. This worked with the game Chuck Yeager's Air Combat.[34]. Vintage Tandy 1000 HX Personal Computer Model 25-1053 No Monitor Power Tested. [citation needed]. A more modern version of Microsoft's BASIC interpreter more closely resembled the MS-DOS GW-BASIC, featuring PC-like functionality. A modified version of the MC-10 was sold in France as the Matra Alice. Furthermore, the Model 4 could be booted with any Model III operating system and emulated the Model III with 100 percent compatibility. [12]) It was also marketed as the Micro Executive Workstation (MEWS).[13]. In October 1979 Tandy began shipping the TRS-80 Model II, which was targeted to the small-business market. 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. Tandy also produced the TRS-80 Color Computer (CoCo), based on the Motorola 6809 processor.
