Version differences:

• Appleii requires "GO LAG" (GO LAGOON) instead of GO TID when it comes to dig the anchor
• Atari requires "DIG ANC" instead of just "DIG" when it comes to dig the anchor
• Several versions (Apple, Atari, potentially more) require you to just "DIG" immediately after "GO BEA" instead of "GO 30"
• TI-99/4A version is the only version with a different spelled dubloon. In TI99 version you need to use "GET DOU" and "DRO DOU" for doubloon.
