I've got one hex comms board and one 3rd party memory that have no
stiffeners, the comms board has plastic blocks on the corners with
extractor levers.  Both are a pain because they flex a lot, and both
are sitting on a shelf somewhere in the workshop, not in a machine.
 Even quad QBus cards without some stiffening are a pain.
