What do you mean by Motorola 68000?
Motorola 68010. The Motorola 68000 (sixty-eight-thousand; also called m68k, Motorola 68k, sixty-eight-kay) is a 16/32-bit complex instruction set computer (CISC) microprocessor, introduced in 1979 by Motorola Semiconductor Products Sector.
Does Motorola still make microprocessors?
Although no modern desktop computers are based on processors in the 680×0 series, derivative processors are still widely used in embedded systems….Motorola 68000 series.

When an operand is stored in a register it is?
Explanation: In a based indexed mode, the operand is stored at a location, whose address is calculated by adding the contents of any of the base registers, with the contents of any of the index registers. 6.
How did the 68000 compare to the 80286?
68000 had one huge advantage over 80286: 68000 had 32-bit registers which meant that it could easily address all of its memory. 80286 had only 16-bit registers so it could directly access only 64 kiB of memory and had to use complicated segmentation system to access all of the memory.
Which is better Intel 8086 or Motorola 68000?
The Motorola 68000 processor was a 32-bit processor internally, with a 16-bit bus, and is generally considered a more advanced processor than the 8086/8088. It was used for the design of computers like the Apple Macintosh, Amiga and Atari and the original Sun Microsystems UNIX machines as well as the Apollo/Domain workstations.
When did the Intel 80286 microprocessor come out?
The Intel 80286 (also marketed as the iAPX 286 and often called Intel 286) is a 16-bit microprocessor that was introduced on February 1, 1982.
What are the instructions for protected mode in 80286?
The 80286 also added new instructions for protected mode: ARPL, CLTS, LAR, LGDT, LIDT, LLDT, LMSW, LSL, LTR, SGDT, SIDT, SLDT, SMSW, STR, VERR, and VERW. Some of the instructions for protected mode can (or must) be used in real mode to set up and switch to protected mode, and a few (such as SMSW and LMSW) are useful for real mode itself.
