some folks are wondering what those metal cans are in the other post. here's a handy reference chart from IBM that shows modules with the lids removed.

SLT: ceramic slab with discrete diodes/transistors
ASLT: two stacked ceramic slabs
SLD: solid logic dense; just more parts crammed on a single slab
MST: ceramic slab with one or more IC die flipped over and soldered down with solder bumps.
