Power-up

In video games, power-ups are objects that instantly benefit or add extra abilities to the game character as a game mechanic. This is in contrast to an item, which may or may not have a benefit and can be used at a time chosen by the player. Although often collected directly through touch, power-ups can sometimes only be gained by collecting several related items, such as the floating letters of the word 'EXTEND' in Bubble Bobble. Well known examples of power-ups that have entered popular culture include the power pellets from Pac-Man (regarded as the first power-up) and the Super Mushroom from Super Mario Bros., which ranked first in UGO Networks' Top 11 Video Game Powerups.

Items that confer power-ups are usually pre-placed in the game world, spawned randomly, dropped by beaten enemies or picked up from opened or smashed containers. They can be differentiated from items in other games, such as role-playing video games, by the fact that they take effect immediately, feature designs that do not necessarily fit into the game world (often used letters or symbols emblazoned on a design), and are found in certain genres of games. Power-ups are mostly found in action-oriented games such as maze games, run and guns, shoot 'em ups, first-person shooters, and platform games.

PowerUP (accelerator)

PowerUP boards were dual-processor 68k–PowerPC accelerator boards designed by Phase5 Digital Products for Amiga computers. They had two different processors working in parallel, sharing the complete address space of the Amiga computer system.

History

In 1995 Amiga Technologies GmbH announced they were going to port AmigaOS to PowerPC. As part of their Power Amiga plan, Amiga Technologies was going to launch new Power Amiga models using the PowerPC 604e RISC CPU and in co-operation with Amiga Technologies Phase5 would release AmigaOS 4-compatible PowerPC accelerator boards for old Amiga 1200, Amiga 3000 and Amiga 4000 models. However, in 1996 Amiga Technologies' parent company ESCOM entered into deep financial problems and could not support Amiga development. Due to a lack of resources, the PowerPC project at Amiga Technologies stalled and Phase5 had to launch accelerators without a PowerPC-native AmigaOS. As a stopgap solution, a new PowerUP kernel was created allowing new PPC-native software run parallel with 68k Amiga OS. To complicate things even further, former Commodore International chief engineer Dave Haynie questioned Phase5's plans to develop PowerPC boards without Amiga Technologies: "Their approach on the software front is kind of a hack, and on the hardware front it's just too much like the old Commodore; at best, they'll wind up with interesting, non-standard, and overpriced machines that can't keep up with the rapid changes in the industry."
