Apple Mac DEC PDP-8/E emulator.

Overview

PDP-8/E Simulator is an emulator for the DEC PDP-8/E minicomputer running on the Apple Mac. The simulated machine is a PDP-8/E with 4K words of memory and optionally a KM8-E Memory Extension (with up to 32K words of memory) and a KE8-E Extended Arithmetic Element. I/O devices are implemented as plugin modules, and plugins for an ASR 33 Console Teletype, an ASR 33 Auxiliary Teletype, a PC8-E High Speed Paper Tape Reader and Punch, a RK8-E Disk Cartridge System, a LP8-E Line Printer and various types of Real Time Clocks are included in the distribution of the simulator. There is also a KC8-EA Programmer´s Console plugin enabling the user to operate the simulator (nearly) like a hardware PDP-8/E, including single step execution on memory cycle level.

Great memories. I am an alumnus of MIT and was one of the "8E" electronic designers working out of the "mill" in Maynard MA in the "60's". All us engineers and DEC President Ken Olsen were ahead "of the curve" back then.

This is an amazing resource - the PDP-8 was a real computer, but simple enough to comprehend. It was commonly used in "machine structures" curricula while those machines survived. Now they're really hard to find (I see one exactly like pictured here, in very poor condition, on eBay for $5,000), so it's great to have this simulator available. I think I'll work on a lesson plan or two based on this amazing tool. If you're curious about learning more - this hilarious video is a good place to start: http://acad.depauw.edu/dharms_web/pdp11/
