680x0 การใช้

• The earliest of these systems were 680x0 based systems running System 7.
• It includes software enhancements for both Power Macintoshes and Macs built around older 680x0 chips.
• Intel CPUs are little-endian, while Motorola 680x0 CPUs are big-endian.
• Many processors, such as the Motorola 680x0, feature a hardware trap upon encountering an illegal instruction.
• This CPU was, however, produced by Philips and not officially part of Motorola's 680x0 lineup.
• It was written in assembly language ( Motorola 680x0 ) by a group of developers who had a reputation for producing extremely efficient code.
• The details of the door were slightly different : two windows for the 680x0 models while the MIPS ones had a single large window.
• Prior to version NEWS-OS 3.9, all versions of NEWS-OS were released exclusively for the 680x0 series of processors.
• It too claims to support only PowerPC Macs, but several readers said its software worked fine on their old Macs with 680x0-family processors.
• The last version of Mac OS that can be run within Basilisk II is Mac OS 8.1, the last 680x0-compatible version.
• System 7 was developed for Macs that used the Motorola 680x0 line of processors, but was ported to the PowerPC after Apple adopted the new processor.
• While the "'SCC68070 "'is mostly binary compatible with the Motorola 68000, there is no equivalent chip in the Motorola 680x0 series.
• The original Motorola 680x0 based system was revised in favor of the PowerPC G3 based system, since the future for the Amigas with 680x0 processors was very uncertain.
• The original Motorola 680x0 based system was revised in favor of the PowerPC G3 based system, since the future for the Amigas with 680x0 processors was very uncertain.
• The vast majority of the operating system kernel was rewritten in VME board computer system vendors were nearing their end of life might have affected the unpopularity of OS-9000 / 680x0.
• This meant that dealing with the dual architecture required very little work for the programmer, and just like the OS, applications themselves could mix and match 680x0 and PowerPC code fairly easily.
• Apple Macintosh computers were initially built with the Motorola 680x0 family of processors, then switched to the PowerPC series; in 2006, they switched to x86-compatible processors made by Intel.
• MacTCP and the previous generation AppleTalk library were slow on PowerPC-based Macintoshes because they were written for previous generation 680x0-based Macintoshes and therefore ran under emulation on PowerPC-based machines.
• NEWS-OS 3.9 was released in both CISC ( " C " ) versions and RISC ( " R " ) versions, for the 680x0 and the MIPS architecture, respectively.
• By the time the 68060 was in production, Motorola had abandoned development of the 680x0-type chips in favor of the PowerPC . The 68060 was the last 680x0-type processor from Motorola.
