They did have the LC PDS and the IIsi could use a NuBus card. Still nothing compared to the II/IIx/IIfx.

Just looked at the back of this HP that I'm about to get up from. There are four slots on this puppy. Can't tell what they are from the outside but they look miniaturized.

Jean-Louis Gassee would be throwing this HP against a wall. Anyone remember his old license plate that read OPEN MAC?
