True in a way. The game was split up because it was too large. It was 
also reimplemented because MDL didn't exist for home computers, and that 
language in it self required too much resources and in general required 
too much of the computer.
A big breakthrough was when they decided, and managed to pull off the

In your dreams. :-)
First of all, I suspect that dumb Frotz still would get into major 
problems with the small address space of a PDP-11. Second, Frotz makes 
some assumptions about file handling that just isn't true on all 
non-Unix systems. And screen handling is a story of it's own.

But people are welcome to try. Heck, I can even offer an RSX machine if 
someone wants to take a shot at it there, with an ANSI C compiler...
It would be interesting to watch, at least. People often just don't 
understand how much Unix-specific stuff is going on in the code.
