While Spectre GCR can already read/write to Mac disks, NO Macintosh-compatible system, Emulator or otherwise, can operate without the Macintosh ROMs, which hold significant parts of the Mac's operating system. So how did they do it? The answer to this question is deceptively obvious: C.E.K.A. has developed a ROM chipset which CLONES the 128K version of Apple's Macintosh ROMs. [description of Mac deleted.] With the exception of Macintosh Emulators. When Dave Small invented this industry in 1986 with the Magic Sac, the only warning that Apple gave was that he could not bundle the Macintosh's ROMs with it. Even though the Magic Sac (and later the Spectre 128) used software to emulate the Mac, it required Apple's Mac ROMs to function. Apple's early attitude resulted in an increasing market for Mac Emulators, such as Spectre 128, Aladdin (a European Mac Emulator), and Readysoft's AMax, a Macintosh emulator for the Amiga. However, it seems that now, with Apple telling dealers not to sell Mac ROMs to anyone using a non-Apple environment, the popularity of Mac Emulators has grown a tad too much for Apple's tastes. And so, with no Macintosh Clones, no Apple ROMs with which to operate Macintosh Emulators, and no competition, it seemed as if Apple's monopoly (as well as its legal department) was going to continue its domination of the industry.... [Description of Phoenix BIOS and IBM clones deleted] James McHugh of C.E.K.A. used a variation of the "Clean Room" method to clone the 128K Apple Macintosh ROMs. Utilizing over twelve books on the Macintosh, including Inside Macintosh Volumes I, II, III, IV, and V (a total of 2224 pages of pure information about the Macintosh), he and his company were able to singlehandedly produce a Clone of the Apple 128K Mac ROMs within a 2 1/2 year period. The result of his labor, collectively termed the "Macintosh Replacement Project", has just recently been completed. According to C.E.K.A, their 128K Mac ROMs are not only completely compatible with Apple's Mac ROMs, but run from 10 to 30 percent faster in most operations, due to the fact that they are written purely in 68000 assembly language (Apple wrote their Mac ROMs using C). Also, C.E.K.A's Mac ROMs are much less buggy than Apple's 128K Mac ROMs, performing some functions (such as memory allocation) more efficiently. However, C.E.K.A. has added a few conveniences to their Mac ROMs which aren't in Apple's Mac ROMs. In order to prevent possible piracy of their Mac ROMs, C.E.K.A stores their Mac ROM code in modified EPROMs designed at IBM's Research Labs, which ERASE themselves if anyone tries to dump their code onto disk using software, or copy them using an EPROM Burner. This, however, brings up some interesting points. There are about 30 badly behaved Macintosh programs that C.E.K.A knows of which make the same illegal memory calls that the EPROMs "protect" themselves against, and if you run any of these programs, you risk losing your ROMs. C.E.K.A. provides a FULL LIST of these programs, and since a pirate may have erased their EPROMs in an attempt to copy C.E.K.A's code using an EPROM Burner, C.E.K.A. will not replace any ROMs that were erased UNLESS the program that triggered the EPROMs into erasing themselves is not on their list of buggy Mac programs. Inconvenient, but since software pirates.... Also, C.E.K.A.'s Mac ROMs provide some defense against any onslaught by Mac viruses. According to C.E.K.A., their Mac ROMs monitor all activity in the Mac's Resource Handler, watching for operations (such as illegal system calls) which, while not common among ordinary Mac programs, are usually used in Mac viruses. If it detects any sign of a Mac virus, a dialog box automatically appears on the screen with a description of the problem, its diagnosis of whether it is virus-related or not, and (in case the program causing the trouble may just be a ill-behaved Mac application) a prompt on whether to eliminate the problem or not.... In response to C.E.K.A.'s work, several of the biggest US computer manufacturers in the industry, and at least one Japanese corporation, are said to both be funding C.E.K.A.'s research with a war chest of around 100 million dollars, and using the C.E.K.A. Mac ROMs as a basis for their own development of Macintosh Compatible computers. Also, C.E.K.A. is planning to make a pseudo-clone of Apple's NEW 256K Mac ROMs. Apple's upcoming revision of their 256K Mac ROMs is said to be upgraded for 32-bit operation, and to have a 32-Bit Color QuickDraw. The difference between C.E.K.A.'s pseudo-256K Mac ROMs and the Apple 256K Mac ROMs will be that Apple's 256K Mac ROMs require a 68020 or 68030 to operate, and C.E.K.A.'s 256K Mac ROMs will be able to function with a 68000 installed. Since some of the Mac "Clones" being made by the companies dealing with C.E.K.A.'s will be announced before the end of 1989, and given that the Japanese have wanted to enter the US computer market for a VERY long time, one could easily see that before 1991.... [description of Atari ST package using Clone chipset deleted] C.E.K.A. is a registered licensee of Apple's System/Finder, so with C.E.K.A. bundling the latest releases of the Mac's System software AND the ac ROMs necessary for its operation, ST Users have "plug in and play" functionality that was lacking in previous Macintosh Emulators. C.E.K.A. is also making versions of their Mac Emulator for the NeXT and Sun Workstations, which will also cost $250.00. Since the NeXT and the Sun run Unix, the C.E.K.A. Mac Emulator uses a special driver to allow them to multitask Macintosh programs as a task under Unix. However, because of some aspects of Unix, the C.E.K.A. Emulator will only be 70 percent Mac Compatible if it is run as a task under Unix. C.E.K.A. also allows Users to let the Emulator take over the machine, using it like an ordinary Macintosh. In this mode, 99 percent Mac Compatibility is assured by C.E.K.A. However, the Mac Emulators for the NeXT and Sun/1 workstations may not appear until the Third or Fourth Quarters of 1989, as C.E.K.A. plans to use their 256K Mac ROMs in those versions of their Mac Emulator to allow the NeXT and Sun to run Mac II software....
