Hey guys, I was looking for the maps for all non-city areas in Ishar3 too, and it looks like
http://solucje.ag.ltd.pl/ishar3.htm is the only place that has any. Not all, but it's better than nothing. As for the polish words, I can help you with that (I'm from Poland).
Map #1 (Time machine)
Brama czasu = Time gate
Kwiatki = Flowers
Maszyna = Machine
Map#2 (Dungeons in the future)
Drzwi lub przejście = Doors or passage
Iluzoryczna ściana = Illusory wall
Przejście tylko w jednym kierunku = One-way only passage
Wajcha = switch
Płyta naciskowa = press-plate
Klucz - Key
Zegar = Clock
Trujący gaz = Poison gas
Brama czasu = Time gate
Klatka z Thiną = Thina's cage
Map #3 (Dungeons in the past)
Drzwi lub przejście = Doors or passage
Wajcha = switch
Płyta naciskowa = press-plate
Klucz - Key
Okno = Window
Brama czasu = Time gate
Smok = Dragon (the one nasty motherf***er you have to kill).
I hope that helps. If you will need to translate something in Polish, use this site:

Cheers!
