- I don't understand this. Why is this more difficult than any other part
- of the emulation? Once the emulation of a target platform is complete,
- anything else is irrelevant. For instance, the current version of Liken
- emulates a Mac Classic. i.e. Software that runs on it has the same
- resources available that would be available on the Mac Classic. If the
- emulation of the target platform is 100% then any thing that runs on the
- Mac Classic will run on the emulator. Of course, the emulation is not
- quite 100% so there are some incompatibilities. This is usually related
- to a program that is using some 'quirky' (read undocumented) behavior of
- the Mac toolbox and the emulation does not 'correctly' model the unusual
- behavior. What is it about "resource compressed" products that would
- fall outside of this model?
-
- For anyone interested, I am running Liken on a HP 720 workstation and get the
- following performance numbers from Speedometer:
-
- CPU: 3.760
- Graphics: 3.284
- Disk: 25.516
- Math: 13.615
- Overall PR: 8.954
-
- The numbers are similar for a 750 except the CPU number is about 4.5.
