Not bad advice paul...but if he can't resist...

The jp6 knobby panel is held on by 3 or 4 silver screws, along the
edge nearest the keys. You take those out, and the whole knob
panel is hinged at the back.  

You can lift it up and look at the wonders inside, but don't flip 
the damn thing open like a lunchbox -- there's all sorts of wiring 
to the controls hooked to the CPU board.  You'll be yanking hard on 
them if you open it up all the way.

The guts of those things are a marvel of japanese hand engineering. Instead
of ribbon cables between the boards and the controls, there are bundles of
multicolored wires that terminate in connectors. the wires are tied together

by hand with little bits of twine. The wiring itself seems to be
single-strand
copper and is quite stiff -- the bundles are carefully bent like piping to
fit where they're supposed to.

They're pretty sturdy in general -- mine flipped backwards off a keyboard
stand once and lived to tell the tale, though I don't recommend doing
this to them.

If I can borrow a digital camera I'll snap some pics of the innards
sometime.

By the way, I've long since lost the screws holding down the control panel,
what with popping Europa beta ROMS in and out.  Does anyone know precisely
what sort of screws I need to buy to replace the lost ones, so I don't strip
out the screwholes?
