tcalc - from the turbo c++ 1.01 version sources. Wee! Retro! This was a spur-of-the-moment conversion from the original Turbo C++ sources to work with ncurses on my linux boxen. I like the colors, the retro-coolness is awesome too. Tried to convert with minimal original source code changes, so most everything is in a 'wedge' between the code and the OS.
