The video hardware of the IIe needs a second bank of RAM to be able to 
display 80-column text or double hi-res graphics, which means there has 
to be a memory card in the auxiliary slot.

The Apple 'Slinky' card is not bank-switched. Instead it uses a system 
more like a disk drive, where the memory is transferred between the card 
and main memory one byte at a time. Even programs like AppleWorks which 
can use the Slinky card as extra memory are really just loading and 
saving chunks of data or code like they would to a disk drive, but doing 
it so quickly that no one notices it.
