# Created 2024-09-27 ven. 13:57 #+title: 7d.nz #+author: Phil. Estival * • [2011-09-02 ven.] Ycalc ycalc, an X Window Calculator, based on Texas Instruments TI-59, by Ulf Nordquist. The development started in 1989. As you can see in the picture below it provides a binary mode, and that's why I like it. ** ./img/ycalc.png Only a slight modification was required to make it compile on Debian. It used to be in the repository but it is no longer. Download ycalc-1.09.2.tgz
