I came up with an idea for a custom Raspberry Pi powered graphing calculator a few months ago, but I have been slightly delayed by the holidays (I host thanksgiving and christmas) so I have not had a great deal of time to work on it. However, I finally finished ordering the parts, and the ones which have not yet arrived are going to arrive by tomorrow. The real problem I am facing is what to flash to my microSD. I want to get normal Raspbian, but its entire concept of a mouse based GUI would make it difficult to transform into a calculator, because I want a system that uses only keys. Besides, I want it to be able to load one thing at a time (namely, some sort of math application that can run on a Pi). On the other hand, Raspbian seems like the only option for using CEmu for the times that I want to run TIOS (as far as I know). If not Raspbian, what would be a good option? My main idea for this calculator is to run a menu. This menu should give options for some program to run, including the option to boot a calculator emulation. Also, I am using a brand new 32 GB microSD, so I probably can get anything. Any suggestions for what to do?
