FLASH-PLAICE is a powerful in-circuit development tool that combines the features of a flash programmer, an emulator, and a high speed multi-channel logic analyzer into one device. It runs uClinux. The logic analyzer features up to 200MHz sampling rates and up to 32 input channels. The logic analyzer Java client features support for up to 200MHz sampling rates, user controlled filtering operations, time line in diagram, metadata (size, rate, and trigger position) stored in files, an ID command for device identification, configurable serial port transfer rate, user configurable drawing modes (logic level, hex value, and scope), and Java client access via almost any PC with a serial port. The Java client uses the RXTX serial library with support for 34 platforms including Linux, Windows, and Solaris. Java client plugins include an SPI and I2C bus protocol analyzer, timing analysis to state analysis conversion, and post-processing functions.
plus4emu is a portable emulator of the Commodore Plus/4 computer. It supports Windows and POSIX platforms (32 bit Windows, 32 and 64 bit Linux, and Mac OS X have been tested). It implements accurate, high quality hardware emulation, but the system requirements are higher than that of most other emulators.
ep128emu is a portable emulator of the Enterprise 64/128, ZX Spectrum 48/128, and Amstrad CPC 464/664/6128 computers supporting Windows and POSIX platforms (32-bit Windows and 32- and 64-bit Linux have been tested). It implements accurate, high quality hardware emulation, but the system requirements are higher than that of most other emulators.
GNS3 is a graphical network simulator that allows you to design complex network topologies. You may run simulations or configure devices ranging from simple workstations to powerful Cisco routers. It is based on Dynamips, an IOS emulator which allows users to run IOS binary images from Cisco Systems and Pemu, a PIXOS emulator to emulate PIX firewalls.
ADTPro transfers disks to and from Apple II and Apple /// computers and the modern world using any of these communications methods: serial/USB, UDP via the Uthernet or LANceGS Ethernet cards, or audio via the Apple's cassette ports. ADTPro has comprehensive bootstrapping support for otherwise diskless Apple IIs. The home page includes extensive tutorials for getting started.
