68000 - The CPU ahead of its time

I found the 68000 easy to program.  The instructions are very straightforward.  i.e. move 8, 16, or 32 bits to a register.  Add two registers.  Move 8, 16, or 32 bits to memory.  It is almost as easy to follow as C code.

Likewise, I found the Z80 easy with its many 16-bit registers.  The 6502 has few registers, which is more difficult to program.  However, the 6502 has a trick, which is zero page instructions that use fewer clock cycles to access the first 256 bytes in memory.  Programmers can use the zero page like registers.
