I posted this in another thread recently, but this will solve all your mapping issues in Might and Magic 1-5
It's a companion app called Where Are We. It adds a beautiful detailed automap, and the overworld is even backgrounded with the hand drawn game maps.
It also adds windows for character stats, inventory, combat, shops, item descriptions, a spell list, and more! It does about everything you could ever want, and it doesn't change or cheat the games. It just gives you easy to see information at a glance.
I wholeheartedly recommend using Where Are We with Might and Magic 1-5. Play around with the options and figure out how you want to arrange your windows that suit you best. The only thing you really need to do on a technical level in edit the Dosbox config file in you might and magic game folder to launch the game windowed at whatever rez you perfer for the size you need the game window. I personally use 1200x900 and i have room for the other windows I need.
