Well... it's a laptop, so it takes up about as much space as the
programmer.  It was given to me, so it didn't cost anything to
acquire.  If you don't already have one, or your only option is a
PC-XT or PC-AT and space is tight, I can see that being a problem, but
in my case, it works great.  When I'm not using it, I close the lid,
then stack the programmer on the closed laptop - not much space at
