Yup, I mounted the 6125 in the top of the rack. The thought indeed did not
occur that you can screw the pin in the metal hinge from the *bottom* side.
I removed the top plastic part with the Data General text (top cover) to
get the clearance space needed to hang the drive on the pins. If you have
a helping hand you can leave the top cover installed. Make sure that the
other guy is holding the drive while *you* screw the pins in :-)
Either way, you have to hang the tape drive on th pins while it is at 90
degrees with the front of the rack (fully "opened" position).

Ughh, that's no fun! If my rack was like that, I would not have noticed
that either. You simply don't expect that, especially because this is
not possible with DEC (or HP) racks. They are either riveted or welded.
Enjoy the disassembly/assembly, a great moment for many pictures :-)
