#Mac perofrma 550 emulator upgrade#
If no such contradictory specs are listed, a stock version of the model must be assumed, even if the required upgrade is extremely common. Note however, a wide variety of cpu and disk upgrade options were available to almost any Mac, the requirements should specify specifically, "800k" or "5.25" or "Harddrive required", 68020 cpu, for instances, if they are listing Mac 128k as an option (running on Mac 128k would require a 68020 and/or drive upgrade). If it says Macintosh 128k, it must include 3.5 400k disks (if it is not a download), unless it states otherwise.
The game must also conform to the drive type specified. The game can be marked with CPU and OS version for every model listed. If it's more than one, just the designation will be listed (IIc, IIvx, 190IIIcs, etc.).

The software packaging and manual might name one or Macintosh models. I've compiled some lists for deducing minimum OS and basic CPU compatibility to apply to game entries (unless contradicted by game packaging).įor now, Lisa hardware and operating systems are included. This allowed his graphics designed for the Lisa to run 60% faster on the Mac speed, not cost, being his motive yet the design decreased cost as well.Īs Apple believes operation systems and detailed hardware specifications are like genitals (hidden away unless/until society accepts them to be clearly visible in public ) but does encourage the listing of individual Mac models in system specs. However, Burrell Smith came up with a "bus-transformer" idea that let them use 8-bit components with a 68000. The 6809 didn't need all those external 32-bit, 24-bit, or even many 16-bit components as it was technically an 8-bit CPU even though it could do 16-bit operations with 16-bit registers. The Macintosh was supposed to be low-cost. A 68000 CPU could be used with all 16-bit components but the Lisa was using 24-bit and 32-bit components (for reasons) making it expensive. In 1979 a prototype Mac board used a 6809 CPU because Apple wanted a system that could calculate in 16-bit. The original Macintosh project overlapped development of the Apple Lisa. dmg file most likely means the game is for OS X. smi file most likely means the game is for OS Classic.Ī.
