Wrong.
If you get a good soldering iron
	someone who can handle it
	one of each HC00, HC139, HC573
	lots of wire
and	the german magazine ST Special
you can make an upgrade to 2.5 M with 41256-12 chips (48 of them).
It works. A friend of mine is working on a board for the chips so you don't
need to build stacks of 4 chips..
