IIc buttons above keyboard?

[K.Grant@its.gu.edu.au (Kevin Grant)]

Hi,

Had a look in the FAQ but couldn't find the answer so I thought I'd ask here.

What do the two thin buttons just above the keyboard to the right of the reset 
button do on the IIc.

The first is marked 80/40 and I assume this has something to do with the built 
in 80 coumn card - Does it switch the card on and off?.

The other has a 3x3 block of black squares - I have a dim recollection from 
when I first owned a IIc that this had something to with the using the Dvorak 
keyboard layout.

Can anyone enlighten me further?

Thanks.

Kev.
