Help !

I've had a problem with the '*' key on the keypad of my ST whereby the keytop
snapped off (ie: the leg that the keytop is part of snapped).  I made the
fatal mistake of gluing the keytop leg back together without taking the  
rest of the keyboard appart - the result of this was that I glued the
key solidly in place !

I then dismanteled the keyboard, unstuck the key and cut away the plastic so
that the key mechanism worked properly.  The problem is that when I came to
put the keyboard together afterwards I discovered that I was one little
rubber 'bit' missing.  The piece I am missing is about 1cm accross and
contains a small graphite block which makes the contact on the PCB.

In cross section it looks like this:

		ttttttttt
		t  KKK  t
		   KKK
		 KKKKKKK
		 KKKKKKK
	           /X\	
                  /   \
-------------------------------------PCB


where the ttt bit is the keytop and the KKKK bit is the key leg.  The
rubber bit I am missing is the /X\ bit above.

Does anyone have any of these (or the whole key mechanism) (eg: from a defunct
ST they may have lying around) ?  Any help gratefully received as I am having
to push a screwdriver through the hole in the keyboard to make contact below
whenever I want to use the '*' on the keypad (which I need quite a lot as it
is 'escape function' when connected to the computer at work).

Thanks

Geoffrey
