PDP-8/E Simulator 1.5.1

PDP-8/E Simulator - An emulator for the Digital Equipment Corporation PDP-8/E minicomputer, a famouse computer of the early 1970
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.

PDP-8/E Simulator applies the GNU General Public License fpr both the simulator and its source code.

What's New in This Release:

  • The (probably never used) opcode 7233 (CLA CML IAC RTR) now correctly set L'AC to 0'6000 with L=0 and to 0'4000 with L=1 (before, L'AC was wrongly set to 0'3000 resp. 0'1000 due to missing parenthesis around the shift in i7233()).
  • In file dialogs, now Mac OS X application bundles are recognized, and the user can choose a Mac OS X application in the preferences for viewing text and log files.
  • The keyboard shortcut command-option-M for the “Minimize All Windows” item in the Windows menu is now functional.
  • To conform to Apples Scripting Interface Guidelines (Technote 2106), the name of the real time clock types in the AppleScript terminology of the Real Time Clock plugin where changed, e. g. now “DK8EA 100 Hz” instead of “DK8EA_100Hz”.
  • To avoid scrolling anomalies in memory inspectors, the inspector window now can only be resized to an even number of content lines when it displays a two line format.
  • In the online help, the homepage URL of the PDP-8/E Simulator was updated.
