PDP 11/45 Emulator v1.8 October 2017. This is that PDP 11/45 emulator which is put together from my earlier PDP 11/70 emulator. Because a PDP 11/45 has less memory it cannot run some of the software a PDP 11/70 can. The PDP 11/45 was released in 1972 and is an older less powerful version of the PDP 11/70 which was released in 1975.
Pdp11.org Dedicated to preserving the history and legacy of the PDP-11 series of 16-bit minicomputers produced by Digital Equipment Corporation from 1970 to 1990, and by Mentec from 1994 onwards. WE WANT YOUR PDP-RELATED MATERIAL! If you have a PDP-11 system, parts of a system, boards, documentation, promotional materials, or anything related to the PDP-11 family of computers, DONT THROW IT OUT! We can help it find a good home, at no cost to you.
We also rescue other DEC hardware. Please for more information.
PDP-8/E Simulator A PDP-8/E Simulator for the Apple Macintosh This is the homepage of the PDP-8/E Simulator, an emulator for the Digital Equipment PDP-8/E minicomputer running on the Apple Macintosh. 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 plug-in modules, and plug-ins for an ASR 33 Console Teletype, an ASR 33 Auxiliary Teletype, a PC8-E High Speed Paper Tape Reader and Punch, and a RK8-E Disk Cartridge System are available. There is also a KC8-EA Programmer's Console plug-in enabling the user to operate the simulator (nearly) like a hardware PDP-8/E, including single step execution on memory cycle level. Furthermore, the simulator has a plug-in for the so that the emulated PDP-8/E can run the. The simulator provides a comfortable user interface for running, writing and debugging PDP-8 software. For each device, there is a separate window which displays the internal state of the device.
The user can view and edit the PDP-8 memory content as octal dump, assembler instructions and typed data (ASCII, integer, floating point.). Other features of the simulator are breakpoints, break opcodes, single step execution, a trace mode for the PDP-8/E and much more. The emulated ASR 33 Teletypes provide all comfort of Macintosh text editor windows and optionally produce the sound of hardware typewriters.
Show that the PDP-8/E Simulator outperforms a hardware PDP-8/E in orders of magnitude when running on reasonable current Macs. There are options to slow down the CPU and the I/O devices to the speed of the real hardware. The simulator passes all of the most important for the PDP-8/E. The plug-in API is included with the download, as well as a Memory Content demo plug-in that graphically shows the PDP-8/E memory content of the running machine.
So you can implement your own plug-ins and PDP-8/E devices using Xcode and Cocoa. PDP-8/E Simulator 2.1 runs on any PowerPC or Intel Mac with Mac OS X 10.4 “Tiger” or better and supports 64-bit mode and macOS 10.14 “Mojave”.
It is a Cocoa reimplementation of the version 1.x for the “classic” Mac OS that was first released in 1994. This version in turn is based on the PDP-8/E emulator of Bill Haygood. All three emulators use the same well-proven PDP-8/E emulation engine. The simulator package includes some PDP-8 software, e. A complete OS/8 system, FOCAL-8 and Pascal-S and a. There are tutorials for a with the PDP-8/E Simulator and for the KC8-EA Programmer’s Console.
For older Macs, there is still PDP-8/E Simulator 1.5.1 available that runs on 68K-, PowerPC- and Intel-based Macs with System 2.0.1 to Mac OS X 10.6 “Snow Leopard”. The screenshot at the left shows the simulator simultaneously running on Mac OS X 10.2 “Jaguar” and on a Mac Plus with System 2.0.1. The Mac Plus “Mr. T” is emulated. This is the for PDP-8/E Simulator 1.x. Note that PDP-8/E Simulator 1.x and the I/O devices can completely be controlled using AppleScript.
Read the of the PDP-8/E Simulator and some. Here are some to other PDP-8 related resources. The PDP-8/E Simulator is published under the conditions of the. Downloads This is the most current version of PDP-8/E Simulator.
The download includes all binaries, some PDP-8 software, the plug-in API and the source code for the simulator:. These are the download files for the “classic” version of PDP-8/E Simulator:. (This is a self extracting archive that requires a classic Mac OS to self-extract.

When you are running Mac OS X without Classic installed, simply drag the archive to StuffIt Expander to unpack. When you get the error message “Safari could not download the file because there is not enough free disk space“ with some Safari and Mac OS X versions, use Firefox to download the file.). (StuffIt Expander 8.0 wrongly reports a damage of the source code archive when extracting it. Use an older version of StuffIt Expander or simply double-click the self extracting archive after decoding the BinHex'ed download. When you get the error message “Safari could not download the file because there is not enough free disk space“ with some Safari and Mac OS X versions, use Firefox to download the file.). (The PDP-8/E Simulator 1.5 distribution contains an OS/8 System Disk with a defective BASIC system. The FORTRAN system of that disk is not able to build a functioning.
Replace the original disk image with this one to be able to run BASIC programs or to build the Adventure game.). (Merge the updated components with the version 1.5 distribution. To extract the self-extracting archive on a Mac without Classic environment, use SuffIt Expander.
