Also, if you look carefully at the back of the case, there are two small
horizontal slots just under the lip of the top of the case.  They were
designed for a small unobtainium tool from DEC that prys open the case top
about 1 cm.  You can use a small thin-bladed flat screwdriver to accomplish
the same thing.  Also, the same screwdriver can be inserted at the very
outside corners of the case, at the back to finish lifting up the top.
Be CAREFUL or the case and screwdriver can be damaged.
