Semi-homework related question: How to make Ti-83 plus say "mem cleared" without actually clearing all program/app memory?

Seriously TI -- it's 2012. The TI-83 Plus has a 96 x 64 resolution LCD. Are you kidding me? You're selling a "graphing" calculator in the year 2012 with about as many pixels as I have fingers?

Texas Instruments released the graphing calculator in 2004, and continues to sell it today. The base model still has 480 kilobytes of ROM and 24 kilobytes of RAM.
