Well, by virus, I didn't necessarily mean "take over the world, destroy data" 
kinda virus...just your average "the program _does_ duplicate itself" sort. 
Sure they wouldn't be practical but I woulda thought they could have been 
written even with less than 32 kb ram.  Actually 32 kb was quite a lot 
compared to some earlier models..
