Torsten Manz has written an HP-15C simulation entirely in Tcl/Tk.

The latest version (1.2.10) of the simulator is available from the simulator home page [http://hp-15c.homepage.t-online.de].

Since version 1.2.08 the simulator supports Windows Vista.

The version available from "The Museum of HP Calculators" is still outdated.
