Manual Disassembly of the Curta
You can better study the individual parts if you move a few parts out of the
way.
Even when parts are completely disconnected they still function, courtesy of
the VRML event system :-)
note:
The Curta is a delicate instrument: it can only be taken apart in a certain
order.
Re-assembly is only possible in the reverse order.
