My, how quickly we forget.  SubLOGIC developed their initial products,
including Flight Simulator, exclusively for the Apple II.  The original
Flight Simulator used monchrome line graphics; it was a big hit.

I'm waiting for an Apple IIGS version.  Because SubLOGIC built
everything the hard way (not only CPU-specific assembly code, but
also their own disk file system), it's taking them longer than it
would have to produce a new port like that.

The real question is, how much of that was really necessary?
I haven't tried to figure out their particular methods, but I know
of ways to do much of what is needed for Flight Simulator in C,
and I know of spiffier flight simulators on real graphics systems
that are coded entirely in C.
