   Welcome to #MOVember, one asm MOV instruction each day.

   The Motorola MC68000 has a BEAST of a MOV instruction.
   Official assembler mnemonic: MOVE. Refreshingly clear!

   You could move to and from registers and/or memory. 8-, 16-, 32- data sizes. Post increment, predecrement. Including memory-to-memory moves (*Ferris Bueller soundtrack voice*: Oh Yeah).

   `*d++ = *s++` is a single instruction in 68000.

   Officially destination on the right: MOVE A7,D0 copies the A7 register to D0
