    SC/MP Processor Emulator

    SC/MP Processor Emulator

    Emulator of the ancient 8 bit microprocessor SC/MP 2

    Emulator of the ancient 8 bit microprocessor ISP-8A 500D/600D or more common "SC/MP" from National Semiconductor. The download contains all sources plus an executable Java Jar file to start right away. Some SC/MP hex dump examples are provided in directory "/etc" as well. The download also contains unit tests and some helping documentation (also in /etc). You may slow down the CPU operations, displaying the CPUs status register as LEDs, to watch the CPU working with its registers. The emulator also contains a VDU (video display unit) output / ASCII input simulation. There are some demos in /etc. And have a look to the NIBL / TINY BASIC interpreter in the TINYBASIC folder, most of the code is over 40 years old. Have fun, Theo Heinrichs

    achtbit

    achtbit

    An 8 bit emulator created on the scratch, including an assembler.

    Ever had the experience of a 8 bit system, having max. 64k memory, using assembler to write effective small programs? This system is an experimental 8 bit, 16 color computer, with a processer similar to Z80, that (on my laptop using linux with NO opengl support) achieves up to 1.2 Million instructions per second and 50 Hz. screen refresh rate. It has a builtin assembler to load assembler programs. There is a rudimentary rom that implements some basic functions like line input, or a system clock. Also there is a snake game, (depending on that rom), as a reference and for fun! Take a look, give me your reply! When having ideas for better performance, let me know!

    Xbpad

    Xbpad

    Xbpad - Use your xbox pad as keyboard and mouse.

    With Xbpad, you can use an Xbox 360® controller to surf the web and play games and music on your PC. It's a comfortable alternative to the keyboard and mouse. Using Xbpad with a wireless controller means you don't need to sit by your computer. You can control your music player wirelessly. You can also connect your computer to your TV and browse the web wirelessly using your controller. Xbpad lets you use a comfortable controller instead of the mouse and keyboard. If you find clicking a mouse difficult, squeezing a controller trigger might be a good alternative. If you need to stay away from the keyboard, you might like to try Xbpad instead. Download: Choose between application bundled with JRE or without.
