Texas Instruments Professional Computer

Last updated

The Texas Instruments Professional Computer (abbreviated TIPC or TI PC) and the Texas Instruments Professional Portable Computer (TIPPC) are personal computers produced by Texas Instruments that were both released on January 31, 1983, and discontinued around 1985; the TIPC is a desktop PC and the TIPPC is a portable version that is fully compatible with it. Both computers were most often used by white-collar information workers and professionals that needed to gather, manipulate and transmit information.

Features and specifications

The TIPC is very similar to the IBM PC both architecturally and from a user-experience perspective, with some technically superior aspects. It is based on the Intel 8088 CPU and an optional Intel 8087 floating point coprocessor. It supports MS-DOS-compatible operating systems, but is not a fully IBM PC compatible computer. Alternative operating systems are CP/M-86, Concurrent CP/M-86, and the UCSD p-System. [1]

The TIPC was reviewed in Byte magazine in its December 1983 issue. [2] The CPU clocked at 5 MHz (a bit faster than the 4.77 MHz of the IBM PC) and has 64 KB of RAM pre-installed. A RAM board can be installed in an expansion slot providing an additional 192 KB or RAM, for a maximum of 256 KB. A later version supports up to 768 KB of total memory. [2] [3] The computer featured 5 expansion slots and has either a 12-inch green-phosphor monochrome (CRT) monitor or a 12-inch color monitor with a color graphics resolution of 720x300 pixels. [2] [3] [1] For text, the display shows 25 lines of 80 columns each. [1] The device has a 5¼-inch floppy disk drive and can support a second floppy drive or a "Winchester" hard drive without requiring the use of an expansion slot or separate chassis, and typically features one of each. [2] [1]

Byte said the keyboard, which has a different layout for the arrow keys and is quieter than the IBM PC, was "well, wonderful". [2] The keyboard has 57 typewriter keys, 5 cursor control keys, 12 function keys and a separate 18-key numeric keypad area. [1] The keyboard has "infinite height adjustment from 5 to 15 degrees slope and connects to the system unit with a telephone-type coiled cord so you can position the key board for greatest comfort (even use it in your lap)". [1] The computer also has the capability to map the keyboard keys to characters to support arbitrary user customization of the keyboard layout. The keyboard ordinarily supports 256 distinct characters to enable international use, and the character set can be expanded to 512 characters for special-purpose applications. [1] A light is provided to indicate uppercase mode selection. [1]

Speech synthesis and speech recognition were added after the initial release, including support of natural-language queries with a relational database. [1]

The Aster CT-80 is a 1982 personal computer developed by the small Dutch company MCP, was sold in its first incarnation as a kit for hobbyists. Later it was sold ready to use. It consisted of several Eurocard PCB's with DIN 41612 connectors, and a backplane all based on a 19-inch rack configuration. It was the first commercially available Dutch personal/home computer. The Aster computer could use the software written for the popular Tandy TRS-80 computer while fixing many of the problems of that computer, but it could also run CP/M software, with a large amount of free memory Transient Program Area, (TPA) and a full 80×25 display, and it could be used as a Videotext terminal. Although the Aster was a clone of the TRS-80 Model I it was in fact more compatible with the TRS-80 Model III and ran all the software of these systems including games. It also had a built-in speaker which was compatible with such games software.

<span class="mw-page-title-main">Datapoint 2200</span> Personal computer and terminal

The Datapoint 2200 was a mass-produced programmable terminal usable as a computer, designed by Computer Terminal Corporation (CTC) founders Phil Ray and Gus Roche and announced by CTC in June 1970. It was initially presented by CTC as a versatile and cost-efficient terminal for connecting to a wide variety of mainframes by loading various terminal emulations from tape rather than being hardwired as most contemporary terminals, including their earlier Datapoint 3300. However, Dave Gust, a CTC salesman, realized that the 2200 could meet Pillsbury Foods's need for a small computer in the field, after which the 2200 was marketed as a stand-alone computer. Its industrial designer John "Jack" Frassanito has later claimed that Ray and Roche always intended the Datapoint 2200 to be a full-blown personal computer, but that they chose to keep quiet about this so as not to concern investors and others. Also significant is the fact that the terminal's multi-chip CPU (processor)'s instruction set became the basis of the Intel 8008 instruction set, which inspired the Intel 8080 instruction set and the x86 instruction set used in the processors for the original IBM PC and its descendants.

The Tandy 2000 is a personal computer introduced by Radio Shack in September 1983 based on the 8 MHz Intel 80186 microprocessor running MS-DOS. By comparison, the IBM PC XT used the older 4.77 MHz Intel 8088 processor, and the IBM PC/AT would later use the newer 6 MHz Intel 80286. Due to the 16-bit data bus and more efficient instruction decoding of the 80186, the Tandy 2000 ran significantly faster than other PC compatibles, and slightly faster than the PC AT. The Tandy 2000 was the company's first computer built around an Intel x86 series microprocessor; previous models used the Zilog Z80 and Motorola 6809 CPUs.

HP-150 was a compact, powerful and innovative computer made by Hewlett-Packard in 1983. It was based on the Intel 8088 CPU and was one of the world's earliest commercialized touch screen computers. Like other "workalike" IBM PC clones of the time, despite running customized MS-DOS versions 2.01, 2.11 and 3.20, the machine was not IBM PC DOS compatible. Its 8088 CPU, rated at 8 MHz, was faster than the 4.77 MHz CPUs used by the IBM PC of that period. Using add-on cards, main memory could be increased from 256 KB to 640 KB. However, its mainboard did not have a slot for the optional Intel 8087 math coprocessor due to space constraints. An HP-150 with an optional hard disk was called HP Touchscreen MAX.

<span class="mw-page-title-main">Rainbow 100</span> DEC microcomputer

The Rainbow 100 is a microcomputer introduced by Digital Equipment Corporation (DEC) in 1982. This desktop unit had a monitor similar to the VT220 and a dual-CPU box with both 4 MHz Zilog Z80 and 4.81 MHz Intel 8088 CPUs. The Rainbow 100 was a triple-use machine: VT100 mode, 8-bit CP/M mode, and CP/M-86 or MS-DOS mode using the 8088. It ultimately failed to in the marketplace which became dominated by the simpler IBM PC and its clones which established the industry standard as compatibility with CP/M became less important than IBM PC compatibility. Writer David Ahl called it a disastrous foray into the personal computer market. The Rainbow was launched along with the similarly packaged DEC Professional and DECmate II which were also not successful. The failure of DEC to gain a significant foothold in the high-volume PC market would be the beginning of the end of the computer hardware industry in New England, as nearly all computer companies located there were focused on minicomputers for large organizations, from DEC to Data General, Wang, Prime, Computervision, Honeywell, and Symbolics Inc.
