where's my map?

Years ago, on the 486 (remember them?) I used to play the Ultima games. I recently found my Ultima 7 CD and remembered how much I enjoyed it. So I then found this program called dosbox from

here

which simulates the old DOS system.
So, I loaded up U7 and started playing...woohoo, just like the old days.
Except, after a bit I had to enter co-ordinates from the map (cloth, no less) that came with the game. It's a protection thingy they used. Until I get the co-ordinates right I can't go any further.
I have no idea where that map is or even whether I still have it at all. AAAAAARRRRRRGGGGGGHHHHHHH!
