hello all; Vswitch on a 1000TX. Opening the cover requires some care, but once inside, it's easy to work on. An external floppy drive could be connected to a port on the back. £6.47 postage.  Both were 13 inch displays and had a power cable and a 9 pin RGB cable to attach to the Tandy CGA port. Many Tandy 1000 enhanced games are featured on YouTube. A later revision of the original Tandy 1000 model was the Tandy 1000A. The 16B was the most popular Unix computer in 1984, with almost 40,000 units sold.. The Model II was not compatible with the Model I and never had the same breadth of available software. The CoCo3 came with 128K RAM, an analog RGB video port, enhanced 640x192 graphics capability, a 64-color palette and much more. 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. Radio Shack offered Tandy 1000 PLUS 300-Baud PC Modem that was compatible with the 1000EX/HX that used PLUS slots. 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. By the mid-80's, it became obvious that the CoCo was lagging behind the competition. The DAC could be used to emulate the Covox Speech Thing via MS-DOS device drivers for limited sound support. The MS-DOS was a version specialized for and only bootable on the Tandy 1000; it included a version of BASICA (Microsoft's Advanced GW-BASIC) with support for the enhanced CGA graphics modes (a.k.a. C $576.71. Released in 1983, the Tandy TRS-80 Model 100 was one of the first truly portable computers. 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. Watch. 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. $89.99. It's first computer, the TRS-80, was the best selling computer until 1980. Alternatively, list the games for a different machine. The RSX still retained the Tandy 1000 3-voice sound hardware and DAC, though the I/O address for the 3-voice sound chip was moved, rendering many games previously compatible with it unable to play music unless modified. 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. Tandy Laptop Computer, Model 200, 1985. 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. It was a small system based on the Motorola 6803 processor and featured 4 KB of RAM. The Z-80 based TRS-80 Model 4 was the most expensive computer you could actually see and touch in any local Radio Shack store.  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. Tandy also produced the TRS-80 Color Computer (CoCo), based on the Motorola 6809 processor. Between 1977 and 1979, it sold 100,000 units. 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. Although less popular than the Model 100, the Tandy 200 was also particularly popular with journalists in the late 1980s and early 1990s. This afforded the user access to popular application software such as MicroPro's Wordstar, Ashton-Tate's dBase II, and Sorcim's Supercalc. Because of the slimline case, only one hard drive could be installed alongside the 1.44 MB 3.5" floppy drive. 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 200 and 600 had enhanced displays and keyboards, at the expense of being less compact. The 1000 RSX featured two 16-bit AT ISA slots. TRS-80 was a brand associated with several desktop microcomputer lines sold by Tandy Corporation through their Radio Shack stores. 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.  Tandy also regained a significant share of the Apple-dominated educational market, which the two companies had once equally shared.  It also came with the option of integrated disk drives. Model 100 woes; 8" drives on Model III? MS-DOS 2.11, DeskMate 1.0, and a keyboard with the same layout as the Tandy 2000's were included with the computer. Mania! 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.  80 Micro approved of the 1000's PC compatibility and stated that the exterior design "gives it a feeling of quality and confidence". For the Casio users, Tandy chose three units from the Casio stable,calling them the Pocket Scientific Computers and emphasizing theiradditional specialized mathematic functions. 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. Unlike the 2000 it would be PC compatible with the IBM PC, and support the PCjr graphics standard. Topics: TRS-80, Radio Shack, Computers. Manufacturer : Radio Shack - Tandy Type : Computer  In early 1983, Tandy switched from TRSDOS-16 to Xenix. With two 4 MB SIMMs installed, the 1000 RSX could be expanded to 9 MB RAM (without using an ISA slot). 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 Tandy 1000 EX featured a 5.25" floppy drive built into the right-hand side of computer casing. Tandy ... TRS-80 Model 100 Portable Computer. 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. In addition, the hardware detection routine for the installer of Microsoft MS-DOS 6 could corrupt the serial EEPROM of Tandy 1000 HX machines. Funky serial on a Model II; Parking a hard card; Tandy SL monitor questions. 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. 128 KB of memory was standard, with the computer accepting up to 640 KB of total memory with the addition of expansion cards. It features Z80A and 68000 processors, 512 KB RAM, … 1985: March - Radio Shack introduces the Tandy 6000 multiuser system. , Original TRS-80 ("Model I") and its successors, Learn how and when to remove this template message, "The Lost Tribes of RadioShack: Tinkerers Search for New Spiritual Home", "The Radio Shack TRS-80 Model III Computer", "Radio Shack goes to Microsoft's XENIX for Model 16 micros", "Tandy introduces the Model 16B computer", "COMPANY NEWS; Digital Sets Plan to Build Its Own PC's", TRS-80 and Tandy-branded computers, clones and related systems, https://en.wikipedia.org/w/index.php?title=List_of_TRS-80_and_Tandy-branded_computers&oldid=989876372, Short description is different from Wikidata, Articles needing additional references from August 2013, All articles needing additional references, Articles with unsourced statements from May 2007, Articles with unsourced statements from June 2008, Creative Commons Attribution-ShareAlike License, This page was last edited on 21 November 2020, at 15:02.
