I have found this useful map for Ishar I in this link http://www.oldgames.sk/en/game/ishar-legend-of-the-fortress/download/2041/
Enjoy it!

Ah, that's awesome. That could make this a little easier.

I´ve opened the .gif with Photoshop, selected the areas and printed them as .PDF.
Then I tried to upload the PDF file to GOG but I got and format file error.
¿Do you know if it´s possible to attach a .pdf?

I do not know. Can you save them as a png file and post them. I do not own Photoshop, but I do own the elements portion of it.

What a good idea!
Here they are. I have divided the maps in four sections so you can print each of them in an single A4.
Enjoy it!

Nicely done thank you! +1 :o)

Excuse me I have seen some more +1 in a few post.
What it means?
It´s courtesy or has a deeper meaning?

If you look in the upper right of a person's post you see a "rate this post" with a + and - button. Clicking on the + give the person +1 and if more people click on it I believe it turns into greater Rep Points. I believe the - will hide the person's post so you no longer have to view it.
Hope that helps. :o)

Generally, here it means you were given 1 "rep point" as a way of acknowledging your contribution. Of course, there could be some who say "+1" only as a form of courtesy, but regulars tend to mean +1 rep by it.
For example, I've also given you +1 for these maps, as they are indeed useful!

Thanks for your explanation!
But .. How can i give +1 to someone?

By clicking on the + sign in the upper right corner of the post, visible when you hover your cursor over the post.

Ops! I used to click "reply" so quickly that I´ve not even noticed ... sorry!
And thanks for your help!
