Free minicomputer software for mac

The PDP-8/E Simulator is an emulator for the Digital Equipment Corporation PDP-8/E minicomputer, a famouse computer of the early 1970 years. The simulator, first released 1994, provides a comfortable user interface for running, writing and debugging PDP-8 software on a Mac and to learn about the internal functioning of a computer.
It has a console with switches and flashing lights enabling the user to operate the PDP-8 like a hardware machine. Maybe the simulator is of interest for a larger audience using it for educational purposes or as a remembrance to the good old time of the computer age.
The simulator and its source code are published under the GNU General Public License.
Enhancements:
- The version 1.5 release includes a TSC8-75 board that enables the emulated PDP-8/E to run the ETOS time sharing operating system.
- Compared to the version 1.5 public beta, there are only minor user interface and Panther compatibility improvements.
