I'm wondering if it is a Pascal version of Moria you are looking for?
If so, I have ported MoriaUB 5.01 (the last version I could find of the original) to modern compilers/platforms in the project MoriaOP (Moria Original Pascal).
I've added some nice features (such as colour, better light radius and much improved inventory handling) as well as fixed some bugs.
You can find MoriaOP at: https://github.com/M3wP/MoriaOP
I hope this helps.
