	 Good Day Dr. Patt,

	 and ran the exact same program on the windows LC3 simulator and it 
	 responded. My question is: Do I need to do something special for the 
	 interrupts on Linux?

Thank you for bringing this to my attention.  Program 5 has been adapted from 
a program 5 that I came up with several years ago.  For some reason, an 
important fact is missing from the write-up: The assignment must be done on 
the Windows Simulator since the Linux Simulator does not implement interrupt 
handling.  

I very much apologize for the inconvenience.  Yes, you need to do this on the 
Windows Simulator.

If anyone has a problem accessing a Windows machine, please let me or one of 
the TAs know.  I do not believe this should be a problem for you, but if it 
is, I will see that you get access to a Windows machine.  The program itself 
should not take you very long, and the learning experience and satisfaction 
from seeing it work is worth it.

See you in class on Wednesday.

And, NOW, I need to get some sleep.
