In this case, we find that one of ordinary skill in the
art would have known of many examples in everyday life where
memory could be either integral or removable. Perhaps the
best example is laptop computers which have a built-in
memory and can have an optional separable memory. The
separable memory, called a PC card or "PCMCIA card," is a
credit-card sized, removable module for portable computers
standardized by PCMCIA (Personal Computer Memory Card
International Association). PC Cards are devices that are
used to attach modems, network adapters, sound cards, radio
transceivers, solid state disks (i.e., semiconductor memory)
and hard disks to a portable computer. Thus, there was
nothing new about devices having built-in and separable
memory. One of ordinary skill in the art at the time of the
invention would have had sufficient knowledge to appreciate
the advantages and disadvantages of built-in versus
separable memory. Separable memory, while requiring its own
housing and connector, has the advantages that information
can be stored in the memory without the need for the
circuitry for playing the information, the memory (with or
without prerecorded information) can be sold without having
