Re: DM42- clock losing time

Mine is from Dec 2017 as well. I set the clock initially but then realized I really didn't care to see it displayed and haven't looked at it since. Currently about 6 minutes fast. It doesn't bother me. Not even sure why there needs to be a clock on the calculator. I'll use my calculator for calculat...

The last one in the TalenPhilips collection is the one I was referring to. It's one of my favorite off-images.

Re: HHGTTG

Someone did post a nice version with the planet and the hitchhiker thumb and those words. I have it on my calculator but I don't remember who made it.

Re: Empty CUSTOM menu

What if, for some reason, you wanted to assign a program to the second row and leave the first blank? :D

Re: Solve Systems of Equation with Complex Coefficients

Perhaps I'm misunderstanding but would it be the same as with a regular matrix but just using a complex matrix? Create the empty matrix, press Enter to duplicate it, then press COMPLEX to create a complex matrix. Then fill in the matrix with the complex numbers? Create correctly sized matrix A, dupl...

Which makes me wonder if I could solder a small 3V cap across the two battery lines to smooth out such brief losses of power.
You could do that Dave. Or you could just, you know, not drop your calculator :D
