Timex Sinclair 2050

Last updated

The Timex Sinclair 2050 (TS2050) [1] [2] [3] [4] [5] was a computer modem built by Westridge Communications for Timex Sinclair, a joint venture between Sinclair Research and Timex Corporation. [6] [7] [8]

Initially sold under the Timex Sinclair [4] label and with a Timex designed case, it was then labeled Westridge 2050, [3] [9] as Timex exited the computer market when the modem started manufacture. [10] A lot of people bought the modem board and made a custom casing.

The device supports all the Timex Sinclair machines, [11] coming with a cassette containing modem control software for T/S 1000 and T/S 1500 on side A and for T/S 2068 on side B. [12]

It was based on the Intel 8251 USART chip and very slow (300 bit/s). A magazine published a way to modify the modem to convert it to a serial port, allowing users to connect faster modems. At least two bulletin board systems based on the T/S 2068 computer and TS2050 modem existed as of 1988. [13]

It was launched in the United Kingdom in March 1981 as the successor to Sinclair's ZX80 and designed to be a low-cost introduction to home computing for the general public. It was hugely successful; more than 1.5 million units were sold. In the United States it was initially sold as the ZX-81 under licence by Timex. Timex later produced its own versions of the ZX81: the Timex Sinclair 1000 and Timex Sinclair 1500. Unauthorized ZX81 clones were produced in several countries.

Z88DK is a Small-C-derived cross compiler for a long list of Z80 based computers. The name derives from the fact that it was originally developed to target the Cambridge Z88. Z88DK is much developed from Small-C and it accepts many features of ANSI C with the notable exception of multi-dimensional arrays and prototyped function pointers. Later version also supports SDCC as compiler.

The Timex Sinclair 1000 was the first computer produced by Timex Sinclair, a joint venture between Timex Corporation and Sinclair Research. It was launched in July 1982, with a US sales price of US$99.95, making it the cheapest home computer at the time; it was advertised as "the first computer under $100". The computer was aimed at regular home users. As purchased, the T/S 1000 was fully assembled and ready to be plugged into home televisions, which served as a video monitor. The T/S 1000 was a slightly modified version of the Sinclair ZX81 with an NTSC RF modulator, for use with North American TVs, instead of PAL for European TVs. The T/S 1000 doubled the onboard RAM from 1 KB to 2 KB; further expandable by 16 KB through the cartridge port. The T/S 1000's casing had slightly more internal shielding but remained the same as Sinclair's, including the membrane keyboard. Just like the ZX81, the T/S 1000 had black-and-white graphics and no sound.

A chiclet keyboard or island-style keyboard is a computer keyboard with keys that form an array of small, flat rectangular or lozenge-shaped rubber or plastic keys that look like erasers or "Chiclets", a brand of chewing gum manufactured in the shape of small squares with rounded corners. It is an evolution of the membrane keyboard, using the same principle of a single rubber sheet with individual electrical switches underneath each key, but with the addition of an additional upper layer which provides superior tactile feedback through a buckling mechanism.

<span class="mw-page-title-main">Home computer</span> Class of microcomputers

Home computers were a class of microcomputers that entered the market in 1977 and became common during the 1980s. They were marketed to consumers as affordable and accessible computers that, for the first time, were intended for the use of a single nontechnical user. These computers were a distinct market segment that typically cost much less than business, scientific or engineering-oriented computers of the time such as those running CP/M or the IBM PC, and were generally less powerful in terms of memory and expandability. However, a home computer often had better graphics and sound than contemporary business computers. Their most common uses were playing video games, but they were also regularly used for word processing and programming.
