The Intel Software Development Emulator is a functional emulator for new and upcoming instruction set extensions. The emulator is based on the Pin dynamic binary instrumentation system (and XED). It emulates the new instructions in the SSE4, AES, PCLMULQDQ, and RTM, BMI1, and BMI2 Intel AVX, AVX2, and AVX512 instruction set extensions. This allows developers to gain familiarity with Intel's upcoming instruction set extensions.
J80 is a Z80 emulator with a standard BIOS for a complete Microcomputer with working CP/M 2.2, CP/M 3.0, and one simple ZX Spectrum 48/128K emulator. The spectrum 128K version emulation is incomplete but working. The goal of this emulator is that the 'hardware' is built on-the-fly, reading the configuration from one file. This makes it very easy to add new peripherals or features.
JMCE a multiple computer emulator, a simulator for 8-bit microprocessors (Intel 8080, Zilog Z80, Intel 8051, etc.) and for many of the computers based over them, such as ZX Spectrum, Altair 8800, and Z80Pack, running their original ROM and operating system. All JMCE computers can be configured programmatically or using XML. For example, it is possible connect the console of a simulated IMSAI 8080 to one TCP server or to one physical serial interface without writing even one line of code. It is also possible to change the memory for the Z80Pack computer from plain to banked memory only by editing a single XML file.
KEGS is an actively-developed Apple IIgs emulator, originally written for HP workstations, improved and customized for Linux. It runs under X at any display depth, and supports changable memory sizes, joysticks, and sound. KEGS boots all Apple II OS variants, and supports all of the graphics modes of the Apple IIgs. It requires a copy of the Apple II system ROMs. Kegs has been adapted to work under Mac OS X, Windows, and the SDL library.
