massmind Hardware Emulation

In particular, there are many programs to make a computer pretend to be:

• another computer, at more-or-less full speed, including sound and video ("emulator") so we can play "classic" dusty old games
• another computer, at slower speed -- or even paused -- ("CPU simulator") so we can debug a program, looking at all the various registers that are practically impossible to access on the real thing.
• a collection of digital logic gates ("digital logic simulator"), so we can design an entire CPU or other digital design -- with the ability to "undo" and quickly make copies of the design, before we build the thing out of discrete TTL or FPGA or ASIC.
• a collection of resistors, capacitors, transistors, etc ("circuit simulator") so we can design a logic gate or audio filter or other analog design -- with the ability to "undo" and analyze the effect of max/min component tolerances, before we build the thing out of discrete transistors or ASIC.
• many other things ... (suggestions ?)

computer emulators

• CHAC History Pages has Apple Macintosh simulators, Apple II simulators, Atari simulators, Beboputer simulator, etc.
• http://www.schorn.ch/cpm/intro.html Altair 8800 simulator. Choice of 8080 or Z80 CPU. CP/M versions. Many languages.
• http://sourceforge.net/projects/winston/ WinSTon - WinSTon is an Atari ST emulator running under Windows. Many programs and games are emulated very well but especially demos still behave strangely. Our goal is the "perfect" emulator.
