I confirmed this privately to Craig, but I think I should tell the rest
of the net as well.  I have done this upgrade myself and it works.  Do
exactly what Craig says and you will have a working 2mb motherboard.  For
desoldering, I used an Ungar 4000 desoldering station.  I also used Augat
machined-pin gold-plated sockets.  Total time to do the upgrade was
approximately eight hours.  It's quite fatiguing to desolder 72 16-pin
chips, so I spread the work out over three nights.  I did this upgrade
in July 1987 and it has been working without a hitch ever since.
