HP15C Calculator



#3

I nearly fell off my chair. I've been using my HP-15C calculator since I was a college student. My parents bought it for me as a Christmas present after a considerable period of pestering on my part. Being state of the art at the time, it cost them what seemed like a fortune. It’s given me years of faithful service without the slightest glitch. I've just been trying to find out how to get the Matrix functions to work (I rarely use it these days and I’ve left the manuals at home) only to discover that my prised possession has become a museum piece!

If you think it's bad you have a museum piece, take a look at eBay and see what your museum piece can fetch at auction!
