I have one of about those dimensions that has four identical rubber
buttons on both top and bottom. The buttons are perhaps 7/8" diameter
and show on the side of the box for about that same dimension. A bit of
judicious work with a small screwdriver will jack mine straight up.
That done, exposes screws on the bottom side, and unused provisions for
same on top. Mine, however, has dual 50-ribbon connectors on it -
definitely SCSI and Apple also.
