As I mentioned, you're probably right with that assumption. But I do NOT
appreciate that...!
  I am!  I am!  :-)   My position, that detail is
important, is
 premised on the belief that if we are committed to preserving the
 history of information technology, we need to preserve the artifacts
 as *working* systems. 
That's quite important. Dead information technology
equipment is by far
more dead than a big steam engine. So it has to be working. The magic
begins when you turn the key and everything starts blinking and moving.
I also consider peripherals very important.
I sometimes wonder why "some" museum people don't really care about
peripherals. I think a working drum printer is harder to get than some
rusty pdp computers (pdpcount 11, printercount 1)....
  UNIX is user friendly.  It's just selective about
who its friends
 are.  
I really like that :)
