Radio Shack already has this. *Tandy FAXBack. *I used it
   extensively when I worked there. *Tandy has available, through
   Faxback, information on EVERY computer Radio Shack ever sold, as
   well as information on the correct perhipherals to use with
   them, how to get them (even third-part items are listed) and how
   much they cost. The database is updated very frequently. Ken
