The user interface has all the controls and displays of the original machine, and the system includes a library of original programs, subroutines, and debugging software. The simulator is intended for use in teaching the history of computing; as a tutorial introduction to the classic “von Neumann” computer; or as an historical experience for current computer practitioners.

EightyOne Sinclair Emulator: EightyOne is an emulator for the range of home computers made by Sinclair Research (and their clones) in the 1980s. As well as emulating the machines themselves, various add-on interfaces are supported, including hi-res graphics, custom character sets, sound and colour cards.

FreeAXP allows unlimited testing of virtual Alpha implementation without commitment to purchase products or services.

Fuse: Fuse (the Free Unix Spectrum Emulator) was originally, and somewhat unsurprisingly, a ZX Spectrum emulator for Unix. However, it has now also been ported to Mac OS X, which may or may not count as a Unix variant depending on your advocacy position. It has also been ported to Windows, the Wii, AmigaOS and MorphOS, which are definitely not Unix variants.

IBM 5110 Emulator: I now wrote a JavaScript emulator of the IBM 5110 to be used directly in the web browser. It is a port of Christian Corti's great emulator, which he wrote for Unix systems. There are probably still some bugs and issues with the keyboard mapping, and disk and tape support are still missing. I am working on it, though, and I am looking for dumps of 5110 disks or tapes to use as test cases.

This device has a powerful and versatile instruction set which allows the system to perform a wide variety of arithmetic, control and decision functions. The microprograms stored in the ROM devices give the designer the power of designing custom computers with standard components.

Multics Wiki: The purpose of this wiki is to provide information to users wishing to run Multics under the DPS8M simulator. While other resources exist on both the subject of Multics and the DPS8M simulator, this Wiki focuses specifically on how to install the simulator and Multics on your machine, how to configure it and administer it, and then how to use it. It differs from the DPS8M-related sites whose focus of attention is on the simulator itself, and from the Multics-related sites, which provide historical, informational, nostalgic, etc. background on Multics. Where appropriate, this site links to those other sites rather than duplicate information.

Nostalgic Computing Center: The Nostalgic Computing Center is a network of virtual computer systems from the 1970's, 1980's, and early 1990's.

Qaop/JS: HTML5 ZX Spectrum emulator.

Real VT102 emulation with MAME: You might have heard of MAME in the context of video-games; after all, it was originally the Multiple Arcade Machine Emulator. However, many arcade machines were built from similar components, hooked together in similar ways, so MAME wound up being a fairly generic “computer components wired together” system, and today it emulates all kinds of computers and game consoles and computerised gadgets as well as arcade machines. In particular, and relevant to our interests, it emulates the VT102. This isn’t documentation-as-feature-list implementation, like xterm or other terminal emulators: MAME uses a copy of the original firmware, and inteprets it with an emulated CPU talking to an emulated serial port and emulated video hardware. This is about the best recreation of a VT102 you can get without taking up half your desk.

RunCPM: Z80 CP/M 2.2 emulator. RunCPM is an application which can execute vintage CP/M 8 bits programs on many modern platforms, like Windows, Mac OS X, Linux, FreeBSD, MS-DOS, Arduino DUE and variants, like the Teensy or ESP32. It can be built both on 32 and 64 bits host environments and should be easily portable to other platforms. RunCPM is fully written in C and in a modular way, so porting to other platforms should be only a matter of writing an abstraction layer file for it. No modification to the main code modules should be necessary.

RunCPM_RPi_Pico: RunCPM for the Raspberry Pico.

Reversing Sinclair's amazing 1974 calculator hack - half the ROM of the HP-35: […] Fortunately Clive Sinclair, head of Sinclair Radionics, had a secret weapon - programming whiz and math PhD Nigel Searle. In a few days in Texas, they came up with new algorithms and wrote the code for the world's first single-chip scientific calculator, somehow programming sine, cosine, tangent, arcsine, arccos, arctan, log, and exponentiation into the chip. The engineers at Texas Instruments were amazed. How did they do it? Up until now it's been a mystery. But through reverse engineering, I've determined the exact algorithms and implemented a simulator that runs the calculator's actual code. The reverse-engineered code along with my detailed comments is in the window below.

TI-99/Sim: Well, here's my contribution to the TI-99/4A community. A few years back, I thought it would be neat to be able to play my old TI games on my PC. Instead of doing the smart thing (looking for an existing emulator), I sat down and wrote my own. At first is was a simple text-based simulation of the TI. Then I added graphical support for the OS/2 Presentation Manager. When I got bored with that, I ported it to Windows and added sound support. Now I've decided to try my hand at a Linux/cross-platform version. In the spirit of Linux and Open Source, I'm releasing the code under the GPL license.

Virtual Colossus: Bringing the world's first electronic computer to you in digital form. Colossus was the name of a series of computers developed by British codebreakers in 1943-1945 to help in the cryptanalysis of the Lorenz cipher. After the war, the Colossus computers were destroyed and all plans and information was required to be incinerated. In 1992, Tony Sale and his team began the ambitious task of rebuilding a working Colossus from scraps of information and a few photos - they succeeded and you can see this running for real at The National Museum of Computing in Bletchley Park. Tony Sale also wrote a virtual version of this amazing machine in 2001, but it's real tricky to get running as it was written for a very old version of Internet Explorer. See if you want to give it a go. To honour his memory and to make sure this code and it's story was not lost, I have rewritten from scratch a new Virtual Colossus using current browsers based on his original logic engine code. My hope is that more people will get to know this incredible story about the first computer.

Virtual T: Virtual T is a TRS-80 Model 100/102/200 emulator that runs on Windows, Linux, and Macintosh. The goal of Virtual T is to provide 100% hardware emulation so any existing programs will run. It also adds powerful development and debugging tools.
