  Design Philosophy Behind Motorola's MC68000 (2)
The MC68000 overcomes this with the ADDI instruction, which allows a byte, word, or long-word immediate value to also be added to an operand in memory using any legal destination-memory addressing mode.
MC68000 op codes are always 16 bits wide, and any arguments the MC68000 requires are always stored as one or more 16-bit words (even if the argument is only a byte quantity).
The MC68000 register set (see the figure) indicates the microprocessor's commitment to long-word data: even though this is a 16-bit machine, all the internal registers are 32 bits wide.

 MundayWeb.com - Motorola MC68000 IDE
My MC68000 IDE does not assemble and emulate the assembly programs itself, it merely creates a development environment.
Therefore, an assembler and emulator for the Motorola MC68000 processor are required in order to use the program.
When the program loads for the first time, it will ask the user where the assembler and emulator can be found.
