Is success in that time an important requirement? You may find it too complicated for the time frame. Help from somebody who has ported to a different platform would probably help. In the specific case of the Z series, you may have significant architectural issues to contend with: the Z series evolved from the 360/370, which didn't even have stacks. I don't know how different the Z series is, but it would be good to find out before you start. > Also, If it's too difficult, can there be any doable goals in the > porting process that I can propose for the program and I would > continue the project even after the program is over.
