HP 9100 display trick


As you probably know, memory is shared between programs and data in HP 9100 calculators. By recalling program code as data you can display strange "numbers". When playing with that feature I ended up with the following oscillation display. Just a curiosity, completely useless, but nevertheless kind of fun.


Nice :-)


Very nice FX and really professional vid3o production ,)



But it's so slow! You need an oscillation overthruster, Dr. Banzai!
