VICE is a Versatile Commodore Emulator, i.e. a program that runs on a Unix, Win32, MS-DOS, Mac OS X, Amiga, or RiscOS machine and executes programs intended for the old 8-bit Commodore computers. The current version emulates the C64, C128, VIC20, Plus4, C64-DTV, all the PETmodels, and the CBM-II (aka C610).
MDK (MIX Development Kit) provides tools for developing and executing, in a MIX virtual machine, MIXAL programs. The MIX is Donald Knuth's mythical computer, described in the first volume of The Art of Computer Programming, which is programmed using MIXAL, the MIX assembly language. MDK includes a MIXAL assembler (mixasm), a MIX virtual machine (mixvm) with a command line interface, a Guile-based virtual machine (mixguile), a GTK+ based GUI (gmixvm), and a mixvm-Emacs interface (mixvm.el). MDK utilities are extensible using Scheme.
uBee512 emulates all of the Microbee Z80 series of microcomputers, including ROM, Floppy and Hard disk-based models. Up to 2MB of extended memory is supported. The optional on board sn76489 sound IC is also emulated. The display may use SDL or OpenGL video rendering. Z80 PIO emulation includes tape, speaker, RTC, serial to PC RS232, and mouse peripherals. Parallel port peripherals include BeeThoven (AY-3-8910), BeeTalker (SP0256-AL2), Compumuse (SN76489), DAC, printer, and joystick. Many disk image types and floppy disks are supported. A joystick may be optionally mapped to keys. A large number of options are available as well as a built in OSD console.
uBeeDisk is a tool that copies disks and images from one to another. It was developed to archive Microbee disk images from floppy disks and to write them back to floppy, but other disk formats can be added. It is intended mainly for users of computer emulators. As the program makes use of the 'LibDsk' library there are many options for image types. The program provides some data recovery methods along with 'info' files for each disk image file created. An 'info' file contains information about the disk image, a status map of all sectors read from the disk, and an MD5 stamp of the associated disk image.
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.
FBZX is another Sinclair Spectrum emulator for Linux, but with an special feature: it works with the framebuffer, so it can work at full speed and full screen. Its main features are extremely accurate emulation of screen and sound (both speaker and AY-3-8912 sound chip), emulation of joysticks (kempston, cursor, and Sinclair), and emulation of 48K (both issue 2 and issue 3), classic 128K, Plus 2, and Plus 2A. It supports Z80 snapshot files (both loading and saving) and TAP files (allowing normal loading or fast-speed loading).
