Question for the day:  Should I keep it even if it finally quit working?  This is the calculator I used when we owned the studio.  I pushed those buttons a lot!  The paper roller quit long ago but otherwise was in fine shape.  Do you think my kids may want it as an antique?  My mom threw a lot of stuff away that became antiques.  :-)  My thought is to remove the keys.  You know how valuable old typewriter keys are now.  Maybe I could incorporate them into some of my jewelry making!  Ideas anyone?
