GNU MDK provides a simulator of D. Knuth's MIX computer, and a
development environment to write, run and debug MIXAL programs on it.
New in this release:
Graphical user interface (gmixvm) updated to gtk+ 2.4.x
gmixvm now uses the latest version of the gtk+ toolkit, including
antialiased Pango fonts.
Individually detachable windows for the virtual machine, the
source window and the devices notebook (there is no 'split mode'
anymore).
Detachable toolbars.
Current source line and breakpoints are now marked via icons.
New menu option to change all fonts at once.
German i18n available (thanks to Mike Scholz). Set LANG to
de_DE.UTF-8 to use it.
mixasm includes debug info in compiled mix files by default: the
options -g and --debug are gone; if you want to compile without
debug info, use -O or --ndebug.
