This caused controversy in the Amiga community when developers thought that phase5 was bringing "too Unixish stuff" to Amiga. It was feared that PowerUP kernel introducing shared objects and dynamic linking would replace the original shared library model and shared objects were indeed adapted into AmigaOS. Another controversy was caused by different designs and purposes of Blizzard PPC and Cyberstorm PPC boards. The Blizzard PPC was designed to fit Amiga 1200 as a standalone device which would not need installing additional software but utilised Amiga's unique AutoConfig feature. This caused problems to some 3rd party developers who developed their own PPC kernels for PowerUP cards since they could not work on Amiga 1200 without removing the PowerUP kernel first. A few hundred titles were released for PowerUP including TurboPrint PPC, Amiga datatypes, MP3 and MPEG players, games (Quake and Doom video games to mention few) and various plugins including Flash Video plugin for Voyager web browser. PowerUP hardware Blizzard 2604e On May 12, 1997, Phase5 announced PowerUP accelerator board for the Amiga 2000 line of computers. The card never got past the prototype stage and hence never released to the public. PowerPC 604e at 150, 180 or 200 MHz 68040 at 25 MHz or 68060 at 50 MHz Four 72 pin SIMM sockets accepting 128 MB RAM, 64 bit wide Ultra Wide SCSI controller Expansion slot for the CyberVision PPC Blizzard PPC Also known as Blizzard 603e, this accelerator board was designed for the Amiga 1200 and plugged into the trapdoor slot. It used a low cost, low end PowerPC 603e processor designed for portable and embedded use. PowerPC 603e at 160, 200 or 240 MHz 68040 or 68LC040 at 25 MHz or 68060 at 50 MHz Two 72 pin SIMM sockets accepting 256 MB RAM, 32 bit wide SCSI II controller (Blizzard 603e+ models only) Expansion slot for the BlizzardVision PPC CyberStorm PPC This accelerator board was designed for the Amiga 3000 and Amiga 4000. The accelerator board was famous for its high performance due to its 64 bit wide memory bus and PowerPC 604e processor. According to Phase 5 it could sustain memory transfers up to 68 MB/s on the 68060 and up to 160 MB/s on the 604e. PowerPC 604e at 150, 180, 200 or 233 MHz 68040 at 25 MHz or 68060 at 50 MHz Four 72 pin SIMM sockets accepting 128 MB RAM, 64 bit
