The aim of this project is to replace the floppy disk drive by an electronic device emulating the floppy disk drive (list of supported Computer/Hardware).
There are two differents emulators:

This is a test done for a dear friend to check if the Acorn Archimedes A420/I is working properly. The RGB scart cable is homemade by me to connect to a Commodore 1085S monitor.

The Acorn Archimedes was Acorn Computers’ first general purpose home computer to be based on their own ARM architecture. Using a RISC design with a 32-bit CPU (26-bit addressing), at its launch in June 1987, the Archimedes was stated as running at 4 MIPS, with a claim of 18 MIPS during tests. The name is commonly used to describe any of Acorn’s contemporary designs based on the same architecture, even where Acorn did not include Archimedes in the official name.
The first models were released in June 1987, as the 300 and 400 series. The 400 series included 4 expansion slots (although a two slot backplane could be added to the 300 series as an official upgrade, and third parties produced their own 4 slot backplanes) and an ST506 controller for an internal hard drive. Both models included the Arthur operating system operating system (later replaced by RISC OS as a paid-for upgrade), BBC BASIC programming language and an emulator for Acorn’s earlier BBC Micro, and were mounted in two-part cases with a small central unit, monitor on top, and a separate keyboard and three-button mouse. All models featured onboard 8 channel stereo sound and were capable of displaying 256 colours on screen.
Four models were initially released with different amounts of memory, the A305, A310, A410 and A440. The 540 was unveiled in September 1990, and included higher speed SCSI and provision for connecting Genlock devices. The 300 and 400 were followed by a number of machines with minor changes and upgrades.

The Apple IIGS (stylized as IIGS) is the fifth and most powerful model in the Apple II series of personal computers produced by Apple Computer. The “GS” in the name stands for Graphics and Sound, referring to its enhanced multimedia capabilities, especially its state-of-the-art sound and music synthesis, which greatly surpassed previous models of the line and most contemporary machines like the Macintosh and IBM PC.
The machine was a radical departure from any previous Apple II, with its true 16-bit architecture, increased processing speed, direct access to megabytes of RAM, wavetable music synthesizer, graphical user interface, and mouse. While still maintaining full backwards compatibility with earlier Apple II models, it blended the Apple II and aspects of Macintosh technology into one. Keeping with Apple’s “Apple II Forever” slogan of the time, the IIGS set forth a promising future and evolutionary advancement of the Apple II line, but Apple paid it relatively little attention as the company increasingly focused on the Macintosh platform.
The Apple IIGS was the first computer produced by Apple to use a color graphical user interface, as well as the “Platinum” (light grey) color scheme and the Apple Desktop Bus interface for keyboards, mice, and other input devices. It was also the first personal computer to come with a built-in “wavetable” sample-based synthesizer chip, utilizing technology from Ensoniq. The machine outsold all other Apple products, including the Macintosh, during its first year in production.

This a special edition of the Commodore C64, celebrating the 1.000.000th sale of the C64 in Germany. This is one of the most desirable Commodore items. There are about 300 golden Commodore C64 produced. The numbers from 1.000.000 until 1.000.100 were for the staff of the Commodore factory Braunschweig.
The rest was given to hard- en software companies, magazine-publishers and distributors. The C64 is a computer system with a keyboard, external power-supply and a motherboard. On the motherboard you will find a MOS 6510 processor, RAM / ROM memory, MOS 6569 VIC-II video chip, MOS 6581 SID sound chip and twice a MOS 6526 CIA. PAL version.

The biggest drawback to the Sinclair ZX-81 or Timex Sinclair 1000 computer is its tiny membrane keyboard.
The Memotech keyboard is the solution to this. With its full stroke keys and standard size, it makes entering data and interacting with programs, so much easier. The bus connector had a Memopak I/F keyboard buffer on it so you could type at a natural pace and the Sinclair could keep up with you.
In most cases this keyboard worked right out of the box, but in some cases with older memory packs, you would need to be sure to place the keyboard last in your chain of accessories plugged into the computer’s bus connector and set the dip switches on the keyboard to “slave”.
The membrane keyboard itself is not disabled while the ZX81 Keyboard is connected and either can be utilized for data input… this makes multiplayer, simultaneous play, much easier as each opponent can use their own keyboard as a controller.

Commodore 64 Shiny Blue (Professional Painting). Many thanks to my friend Damiano Colombari (Manosoft)
CBM prg Studio Version 3.0.0 is released. There are a lot of new features in this version. I’d really appreciate it if you report any bugs you find or have any suggestions/comments.
CBM prg Studio allows you to type a BASIC or Machine Code program in using a nice Windows environment and convert it to a ‘.prg’ file which you can run on an emulator, or even a real C64 / VIC20 or PET if you’re feeling brave and have the right kit.
CBM prg Studio is the result of merging C64PrgGen and VIC20PrgGen. Adding new features and fixing bugs in two apps which were 95% similar was a bit of a nightmare so merging them made sense.
It was also a good opportunity for a face lift and to add some new features, such as:
What CBM prg Studio isn’t is a front-end for tok64, cbmcnvrt, bastext or any other tokeniser / detokeniser / assembler. It’s all been written completely from scratch.
New features:

Relaunch64 is an IDE (text-editor) for C64 assembler-coding on Windows, Linux and Mac OS X. Relaunch64 has a clean and intuitive user interface, yet it offers many features that make coding faster and easier.
Java 7 or higher is required to run Relaunch64. The program is licensed under the GNU GPL 3 (or higher) and free for private and professional use.
This editor works together with common cross assemblers like Kick Assembler, ACME, or 64tass. Other assemblers might work as well, but syntax highlighting may not be 100% correct.
