Dave's DVD player remote has the same battery as my first graphing calculator (which used three), the Casio 7500, which had 26 user accessible registers and a whole 4 kilobytes of NVRAM. The manual that came with it had a program you could enter into the calculator to solve quadratic equations. I wrote my first program on that machine, a clock that updated every minute, that had a timing loop that had to be hand adjusted.
Sigh.
Did I mention the battery in the remote is almost dead.
Dave? Are you listening? You need 1 CR2025 battery.
