Couple of remarks here: the interpretive emulation reaches speeds of around 68040/40 on a Cyberstorm PPC @ 200 Mhz.

Most modules on the demo are still 68K as we are now putting into place the tools (OS 4 native compiler, source-code conversion tools etc.)  to migrate the whole OS to PPC.

Once this is done, I don't expect migration to take more than 2 weeks tops considering  the number of developers with a PPC.

This is based on our experience porting SFS, CDFS, cia.resource, timer.device etc. to OS 4 native.

With respect to the JIT, it is ready to be integrated into the system.

I'd say so, yes although I'll be damned if I'd stake my life on it.

You are for instance referring to the fact that no apps running under emulation were shown.

This is a fair comment and I'll ask that some apps are shown next time (I suspect they were not shown because it is not always clear to people that they are running on OS 4 and that the emulation speed is bound to go beyond 060/50 with the JIT).

But whilst we have not run a vast variety of apps, we have tested things like Wordworth, DirOpus 4, PPaint, some games like Colonization, Ibrowse, YAM etc.

The JIT is ready for integration, Almos is doing an OS 4 application launcher, Alex will integrate that into the system.

Meanwhile, we're cleaning up some outstanding bugs and cosmetic issues pending arrival of a full OS 4 native toolchain.

Once that's done, we don't expect that it will take too long for modules to be migrated. We have already migrated some complex ones like SFS or timer.device and those didn't pose any significant issues.

OS 4 native compiler with C runtime library, tools to convert source-code from OS 3.x to OS 4.0 target etc.

We'll release everything we have in terms of tools at the time OS 4 comes out.

That includes an easy to install "ixemul" free GCC compiler as Olaf Barthel did his own C runtime library which we have been busy porting to PPC.

Plus all the tools we are doing to migrate source-code, examples to write OS 4 native code (devices, libraries etc.).

A full developer CD should come out shortly after OS 4.
