PDP-8-E Simulator for MAC

PDP-8/E simulator simulates the DEC PDP-8/E computer running on an Apple Mac. The simulated machine is a PDP-8/E minicomputer with 4K words and optionally a KM8E Memory Extension (with up 32K words) and a KE8E Extended Arithmetic Ellement. The simulator includes plugin modules that allow I/O devices to be implemented. These include plugins for an ASR 33 Console Teletype and an ASR 33 Auxiliary Teletype, as well as plugins for an ASR 33 Teletype and an ASR 33 Auxiliary Teletype. A KC8-EA Programmer’s Console plugin allows the user to operate (nearly), the simulator like a hardware PDP-8/E. This plugin includes single step execution at the memory cycle level.

Version 2.3

• The PDP-8/E Simulator now runs natively on Macs with Apple silicon
• The KC8-EA and TC08 lights no longer flicker so much, they now glow more like real bulbs
• Nicer TC08 indicator panel
• Improved timing for the TU55 drives lets the DECtape formatter DEC-08-EUFB-PB run more reliably on fast Macs and speeds up the DECtape in normal operation
