The Catweasel Floppy Read/Write Tools are a set of tools for owners of Catweasel MK1 ISA and Catweasel MK3/MK4 PCI universal floppy disk controllers. cw2dmk reads several kinds of floppy disk, some of which ordinary PC controllers have trouble with, and save them in the DMK disk image format used by TRS-80 emulators. It can also handle any disk written using a Western Digital 177x/179x floppy disk controller, a PC-style NEC765-compatible controller, or a Digital Equipment Corporation RX02 controller. dmk2cw writes any DMK image back to a floppy. jv2dmk and dmk2jv3 convert images between DMK and JV1 and JV3 formats without requiring Catweasel hardware.
gRustibus is a M.A.M.E. frontend for the GNOME environment. Its goal is to be feature-rich and easy to use. It shows screenshots, flyers, cabinet photos, and info for your M.A.M.E. ROMs, and allows you to configure each game individually. Most operations can be done using the keyboard.
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.
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.
spim is a self-contained software simulator for running R2000/R3000 assembly language programs. It reads and can immediately execute files containing assembly language code. spim also provides a debugger and simple set of operating system services. spim provides both a simple, textual interface and a fancier, graphical interface. The package includes complete source code and documentation.
