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...)
