RE: [MI400] a working ppc emulator

Steve,

That's very interesting about the long jump.  I will have to see if I can
find that thread.  

Yes, I think it would fascinating to experiment with the iSeries PowerPC OS
on other platforms such as the PowerPC emulator, or maybe another hardware
platform which implements the PowerPC chip like the Mac desktop or server.

Since an iSeries with a blank hard disk can IPL far enough to format the
hard disk and install the rest of the OS simply by inserting the first OS
CD-ROM, that would be a good place to start.

Matt

Any kind of a low level project like this is a great idea.  My interest is
in porting a powerpc compiler from the Mac or some such platform to the
as400.  Compiling and running a powerpc assembler program on the 400 would
be fantastic. We had a discussion on this list a long time ago on how the
powerpc long jump can branch the program execution to any 64 bit address.
Which on the 400 means you can jump to code that resides in an external
object like a user space. That sort of facility looks to me to be the
foundation of how you would extend the object model of the system.

Matt, as far as what you are proposing, are you suggesting running as400
powerpc byte code on a PC?  I am interested just to know how to do it.  How
would you get the object code off of the as400 onto the pc?
