The Compact Computer 40, or CC-40, is a notebook-sized computer developed by Texas Instruments. It started development in 1981, [ 1 ] and was released in March 1983 for US$249. The CC-40 has a single-line 31 character LCD display, weighs 600 grams (21 ounces) and is powered by an AC adapter or can operate for 200 hours on four AA batteries .
Compaq's efforts were possible because IBM had used mostly off-the-shelf parts for the PC and published full technical documentation for it, and because Microsoft had kept the right to license MS-DOS to other computer manufacturers. The only difficulty was the BIOS, because it contained IBM's copyrighted code.
A single-board computer (SBC) is a complete computer built on a single circuit board, with microprocessor(s), memory, input/output (I/O) and other features required of a functional computer. Single-board computers are commonly made as demonstration or development systems, for educational systems, or for use as embedded computer controllers .
The MIT Suitcase Computer, constructed in 1975, was the first known microprocessor-based portable computer. It was based on the Motorola 6800. Constructed in a Samsonite suitcase approximately 20 by 30 by 8 inches (510 mm × 760 mm × 200 mm) and weighing approximately 20 lb (9.1 kg), it had 4K of SRAM, a serial port to accept downloaded ...
TI-99/2, [45] a 4K RAM, 32K ROM computer with no color, sound, or joystick port and a Mylar keyboard. TI designed the computer in four and a half months to sell for under $100 and compete with the Sinclair ZX81 and Timex Sinclair 1000. Based on the TMS9995 CPU running at 10.7 MHz and with a built-in RF modulator, performance greatly increased ...
A minicomputer, or colloquially mini, is a type of general-purpose computer mostly developed from the mid-1960s, [1] [2] built significantly smaller and sold at a much lower price than mainframe [3] and mid-size computers from IBM and its direct competitors [dubious – discuss]. By 21st century-standards however, a mini is an exceptionally ...
