Went to the Macworld Exposition in S.F. today and bought an upgrade kit for
$250 (sorry, but that was a special show price, normal price is $350).
The kit was made by:

	Micro Conversions
	3606 Knoll Crest Dr.
	Arlington, TX 76014
	(817) 465-5758

It contains:

	Torx screwdriver
	Small wire cutters
	IC insertion tool
	Very pointy tweezers
	X-Acto knife
	3 rolls of desoldering braid
	A very good set of instructions
	74F253 multiplexer
	17 256k RAMs (1 spare )
	17 Low profile sockets
	1 minature PC board for "Old Style" motherboards
	Resistors and capacitor for multiplexing circuit

As you see, it is a very complete kit.  All you need to add is solder, a
soldering iron, and a few (3 to 4) hours of your time.  I was very careful
and was rewarded by having my Mac test out OK on the first power-up.

The minature PC board mentioned above allows for a very clean upgrade on
an "Old" Mac.  It solders into the 7 holes right next to the 68000, and
there are none of the unsightly jumper wires like those used in the upgrade
shown in Dr. Dobbs Journal.

A 512k Mac with a RamDisk turns out to be THE fix for MacTerminal's 
whiring disk annoyance (among other things).
