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).
Red language is a native-code compiled functional, imperative, symbolic, and homoiconic programming language that re-uses most of REBOL's syntax and semantics. Both static and JIT compilation support are planned. A strong emphasis is made on concurrency and both task and data parallelism support using an actor-like abstraction and parallel collections (Scala-like). The target range of usage spreads from low-level system programming (thanks to the built-in Red/System C-level DSL) and embedded systems, up to high-level scripting, with an optional REPL console.
KernelDriver automates your Windows 2000/NT, Windows Me/98/95 and Linux device driver development by providing you with powerful tools for hardware debugging, driver code generation, and driver debugging. KernelDriver supports PCI / USB / ISA and EISA drivers. KernelDriver for Windows and Linux includes the powerful Driver Wizard. Using the Driver Wizard you can graphically debug your hardware by "peeking" and "poking" at it without writing a single line of code. After your hardware is diagnosed, use the Driver Wizard to generate a complete kernel mode device driver which will drive your hardware.
FIGlet is a program for making large letters out of ordinary text. It prints its input using large characters made up of ordinary screen characters. FIGlet output is generally reminiscent of the sort of "signatures" many people like to put at the end of email and UseNet messages. It is also reminiscent of the output of some banner programs, although it is oriented normally, not sideways.
Dapple ][ is an emulator for the Apple ][, ][+, and //e computers (and to some extent the //c) supporting from 48-3136 K RAM, parallel ports, 2 Disk ][ drives, and a real 1.40 MB floppy drive. It is written in gcc and nasm (the nasm component is not currently source-available). It supersedes Dapple, which has many of the same features.
