Earlier versions were bundled with systems so again to use for instance System 6.0.8 one has to have a Macintosh.

#Mac 68040 emulator full#

However since only System 7.1 and later are or have been commercially available and implementation of full System 7 support for emulators poses some serious challenges, an earlier version is more suitable. A usage right for this can be bought from any Apple outlet.

The second important software component ofcourse is the MacOS. This has never been brought to court so there is no jurisdiction about it. The concept here is that when you own a Macintosh Plus you are entitled to do this. vMac relies on you to extract the contents from the ROM of a Macintosh Plus and to transfer it to your vMac directory. Ardi does not use any ROM component from Apple. Since Apple does not distribute the ROM code, there is no other way than getting this component legally by actually buying a system. This is a very lengthy and tedious process. Since it can never contain an exact copy of the Toolbox, since that would violate Apple's copyright, and because Ardi cannot reverse engineer the Toolbox calls because then the result would be 'dirty' meaning that Apple could probably sue them, the Toolbox calls are 'reconstructed' by examining which call is called how and what should be returned to the caller. The Toolbox has thousands of calls which Executor tries to emulate. There are two components to emulate here the Macintosh Toolbox, which in a real Mac is contained in ROM and the MacOS, which loads from harddisk. Most important is the quality of the emulation of the software that controls the hardware.

There is sound support, printing and feature versions will have full serial support. floppies as well as SCSI harddisks, CD-ROMs and removables. Within the Macintosh systems architecture ofcourse the various hardware components play an important role and Executor succeeds in emulating it to a certain extent Executor reads Macintosh 1.44 Mb. VMac and Executor (both on a Pentium 166) compared against a 0 More info is available on Ardi's web site. (The issue here is called little-endian versus big-endian, from Jonathan Swift's Gulliver's Travels where there is a war between two armies about at which end of an egg one would have to start eating.)Д®xecutor's 68040 CPU emulator is very fast because it uses dynamic compilation, which means that for instance within a loop the instructions within the loop are translated once and not every time one single instruction is executed. Not only does one have to 'translate' every 680x0 machine instruction to i486 code, there are also issues involved like the fact that the byte-order of 16 bit words is different between the two families of processors.

Ofcourse a PC has no 68040 processor so the first main task of every person trying to write an emulator is to emulate the processor.

On a 486 processor the emulation is as fast as the real thing. there is no Finder interface but a substitute (which the founder of Ardi once called 'Looser') has been put in place.Д®xecutor emulates the hardware of a Macintosh with an 68040 processor without FPU and MMU (the latter being provided by the host OS), which puts it in the Quadra class. Also the look-and-feel of Executor (when not within an application) is different from a real Mac, i.e. The somewhat technical term is that they are 'clean', meaning that Apple would have no legal case against them.

Ardi never used any code from Apple and has never disassembled or even looked at Apple's code. Development started on a PDP-11 (!) and the first beta ran on a SUN-3.ДЇrom that on the environment was developed into Executor. To have a demo of what the libraries could do, Ardi developed an environment for the libraries so that they could show Word running on a UNIX box. The goal was to develop a set of libraries for UNIX to ease porting of applications originally developed for the Macintosh. The developers literally started with nothing except lots of public information about the Macintosh (like the Inside Macintosh series of technical manuals). To compare these two is comparing apples and oranges (pun intended), however a number of people have raised questions that the following might answer.Д®xecutor was developed from ground zero.

Both emulate a Macintosh and both are developed with the DJGPP GNU C compiler. These two emulators have little in common. Executor versus vMac Executor versus vMac
