No silly.  The best thing to do would be to write a PC simulator for the 
Cray.  You could emulate 8088 assembler, the port mapped I/O, and memory
mapped video.  Then you link into it a small loader and flight simulator,
so when you run the cray executable, it will emulate a PC and then run 
flight simulator.  To cope with the superfast speed, tell the emulator
to suspend itself for so many microseconds after interpreting each 
instruction.  Just my $0.02
