Apple II processor cards (or co-processor cards) were special cards that could be used to allow the Apple II to use different processors on the (otherwise) same computer hardware. This allowed other operating systems to run on the Apple II. Here are some processors that were available on coprocessor cards for the Apple II: * Zilog Z80 – Microsoft SoftCard or compatibles, ran CP/M〔(Microsoft Softcard ), Microsoft Consumer Products. (1980), A2Info.Net〕 * Intel 8088 – the AD8088 Processor Card, from ALF Products, ran CP/M-86 and MS-DOS as well as increased the speed of math functions in Applesoft BASIC.〔ALF Products newsletter, 1983, (''ALF Alpha 5'' ). Retrieved 2013-04-13.〕 MetaCard, from Metamorphic Systems (a 1980 startup by Phil Zimmermann), ran CP/M-86, MS-DOS, and UCSD Pascal〔(Two new 16bit processor cards turn Apples into IBM PCs ), By David Needle, 12 Apr 1982 InfoWorld〕 * Motorola 6809 – The Mill, by Stellation Two, ran OS-9 Level One.〔(The Mill by Stellation Two )〕〔(Romance of the Entrepreneur ), The Capitol of Romance〕〔("THE MILL" carte 6809 de STELLATION TWO ), HACK Z APPLE, Collection Apple II〕〔(James Hinds ), CHIEF DESIGNER & PRESIDENT, Stellation Two, Inc. 1/1980-6/1985 – invented, designed and produced THE MILL and Vitamill coprocessor circuit boards for Apple // computers for this manufacturer of hardware and publisher of software for Apple // Computers.〕 AP10 by IBS running FLEX * Motorola 68008 – mc magazine〔(Apple II 68008 Co Processorcard project )〕 * DEC LSI-11 – (unconfirmed) ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Apple II processor cards」の詳細全文を読む スポンサード リンク
