 is going to be a development machine as all the switches and display

 I don't think National made many minicomputer format machines, in
 their history, someone correct me. That might make this pretty rare
 on that front as well.

  Yeah, it's pretty cool but I don't think the seller has reasonable
 expectations for actually selling it -- the auction started (I believe)
 at $1500 (which may have been a reasonable price), then the seller
 raised it to $2500, now it's at $3500 (which is fairly outrageous, in my
  opinion). I'm not sure what his strategy is.
 Bitsavers has manuals (of course...)

 I think he figured toggle switches and lights = $$$$. He might be correct,
given the obscene money I've seen laid out just for a PDP 8/e faceplate. You never
know a) what will motivate a collector and b) when just the right collector for a given
item will show up. Every day I thank my lucky stars they didn't, for whatever reason,
show up for my Mark-8 boards. 
With the "No shipping cash on pickup" proviso the seller provides, I
feel fairly certain no one's biting. But I've been surprised before...
