LC2 ISA Simulator / News: Recent posts

LC-3 Sim 1.0

I am pleased to announce release 1.0. This entails a port to Java, a function (and about on par with the ncurses) Swing based interface, and some other goodies. There is still room for improvement but this is a functional release that is better then our metric (BYU's original LC-3 Simulator)

Now that I (Ed Page) am back around, there are a lot of updates in CVS. It now works with LC-3, has a lot of bug fixes, and is moving more towards a true C++ program rather then mixed C/C++ style code. Tere is a tenative GTK user interface, but that is on hold slightly.

New GTK UI under development

lc2sim-gtk-linux and lc2sim-gtk-windows are actively under development at the moment.

We hope to take advantage of the GTK-curses project to bring the nice UI to the console, allowing a completely uniform UI across platforms.

Also, a major rework of the processor core is underway to allow for developers to more easily interface with the simulator libraries.
