[time-nuts] how to open a Trimble mushroom ?

[Pete Lancashire]

More goodies from storage

I have a few 'special' Trimble mushroom GPS's. I'm trying to open one up
but can't seem to get very far. I've pulled all the tabs out but still can't pry
the case open.

They interface between the two sections doesn't look welded or glued.

Here a couple picts

The data on these guys was trashed long ago when the company closed
up. I could not locate it anywhere.
