Numerous programs cancompute an md5 checksum. I have also provided a "ROM md5 Checksum" where Iknow it, which can provide a much stronger assurance thatyou have an undamaged ROM.

(Since Mini vMac modifies the ROM, it willfirst make this check itself, and then disable thechecking code in ROM.) A Macintosh willcompute this sum on startup to help make sure the ROM isundamaged.

It is usually a simple 32 bit sum of all 16 bitvalues in the ROM, excluding the checksum. The "ROM Checksum" is stored in the first 4 bytesof the ROM. To emulate any machine other than aMac Plus, Mini vMac needs to be recompiled (See the" Options"documentation). It is also the name of the file that Mini vMac will look for,if Mini vMac supports that ROM (in which case the entry includes theline "Supported by Mini vMac: yes"). "Rom Image Name"is the name of the file that my CopyRoms programwill save. This list is grouped by ROM version (different Macintosh models canshare the same ROM), and sorted by initial sale date. It may not be too accurate, it is just my bestguess from gathering information from many conflicting sources.

Mac OS 8 and the following updates brought a promised refresh of Mac OS, but more importantly, the paid upgrade injected much-needed cash for Apple.Here is a some information about 680x0 Macintosh models that could beuseful to emulator users. While Apple was shifting direction to release for its operating system, Apple needed to keep the Mac platform alive until OS X was released four years later. Jobs shoved Mac OS 8 out the door as the first operating system under his return.
This search resulted in purchasing NeXT and the return of Steve Jobs. These struggles led Apple to look outside the company for its next-generation operating system.
The company struggled for years to release a revamped operating system under the codename, Copland. Mac OS 8 was a pivotal release for Apple in 1997.

It seems fitting an emulator for Mac OS 8.1 comes as Apple embarks on another processor shift to ARM-based processors. Going forward, Mac OS would require a PowerPC processor. Mac OS 8.1 was the final OS to support the original Motorola 68000-series processors. I've got a lot of memories of Civ II and Duke Nukem 3D running Mac OS 8 back on my Performa, I think 6300 if I remember. There's even a bunch of apps and trials preinstalled, including Photoshop 3, Premiere 4, Illustrator 5.5, StuffIt Expander, and Apple's Web Page Construction Kit. Rieseberg has managed to get classic games like Duke Nukem 3D, Civilization II, Dungeons & Dragons, Namely, Oregon Trail, Alley 19 Bowling, and Damage Incorporated running. The macintosh.js app is written entirely in JavaScript, and it uses a virtual machine to emulate a Macintosh Quadra 900 with the Motorola CPU Apple used before its transition to IBM's PowerPC chips.

The developer that brought us Windows 98 emulator for kicks has developed an emulator for Mac OS 8.1.
