Sinclair ZX Spectrum
Sir Clives Sinclair third strike was the Sinclair ZX Spectrum. The successor of the ZX81 was equipped with color graphic (16 colors) and a resolution of 256*192. The membrane keyboard was replaced by a rubber/eraser stylish keyboard. The main memory was extended to 16 KByte and 48 KB in the Spectrum 48K. Sinclair's Spectrum was mainly successfull in the U.K. and had various successors.
At the end of the year a small british company tried to sold a new computer called Dragon. It sold well first but there were problems including the slow development of new peripherals and the slow production of new units. The company tried to sell the computer in the U.S. but they failed.
The computer itself was quite interesting: it featured an uncommon CPU (the 6809) which was clocked at 0.89 MHz but faster than most other CPU's with a higher clock rate. OS/9 could be used as an operating system which was later ported to the Atari ST.
The successor of the VC20 was published in the USA: the C64 which became soon the most popular homecomputer of all times. The public was amazed how Commodore could pack so much graphic and sound into one computer. First games were presented in the same year like the classic Infocom adventures Zork and Stationfall.
CP/M was still strong in 1982. One of the machines which were running CP/M was the Kaypro II. Delivered with a software package, a 9" green screen and a disk drive (5.25" 193 KB) it was quite a complete system.
The HX20, one of the first portable computers was announced by Epson. Internal power supply using batteries, a built-in mini cassette recorder and printer and a LCD display made it quite popular for some people. Special applications e.g. for doctors were developed.
A new and still unique video game system was available: the Vectrex by GCE (US-$ 200). The display was built-in for one reason: it was a vector monitor. Instead of drawing pixel by pixel the screen draws lines. Before the Vectrex the technology was only used in arcade machines. Therefore a lot of arcade conversions of an excellent quality were available.
Corvus introduced the Concept computer - a real workstation. Using an 68000 CPU clocked at 8 MHz and 256 KB RAM it was an impressing machine at that time. The most innovative thing was probably the screen: it could display a full page! The Corvus Concept wasn't really a home computer (price: 5000 US-$) the 68000 technology came to the mass market three years later.
