- the gmeboy hand held. Handheld electronic games had been popular for more than a decade by the time Nintendo introduces the Game Boy. The system used removable game cartridges to play on its 2.9-inch black and white screen. Game Boy's popularity was helped by its major release title, the puzzle game Tetris. Over nearly twenty years, more than one hundred million Game Boys were sold, making it one of the all-time, top-selling game systems.
- Intel released the 80486 microprocessor and the i860 RISC/coprocessor chip, each of which contained more than 1 million transistors. The RISC microprocessor had a 32-bit integer arithmetic and logic unit (the part of the CPU that performs operations such as addition and subtraction), a 64-bit floating-point unit, and a clock rate of 33 MHz.
The 486 chips remained similar in structure to their predecessors, the 386 chips. What set the 486 apart was its optimized instruction set, with an on-chip unified instruction and data cache and an optional on-chip floating-point unit. Combined with an enhanced bus interface unit, the microprocessor doubled the performance of the 386 without increasing the clock rate.
- Macintosh portable. Apple had initially included a handle in their Macintosh computers to encourage users to take their Macs on the go, though not until five years after the initial introduction does Apple introduce a true portable computer. The Macintosh Portable was heavy, weighing sixteen pounds, and expensive (US$6,500). Sales were weaker than projected, despite being widely praised by the press for its active matrix display, removable trackball, and high performance. The line was discontinued less than two years later.
