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? -Steve -----Original Message----- From: mi400-bounces@xxxxxxxxxxxx [mailto:mi400-bounces@xxxxxxxxxxxx]On Behalf Of Matthew D. Frederes Sent: Saturday, June 26, 2004 6:50 PM To: mi400@xxxxxxxxxxxx Subject: [MI400] a working ppc emulator There is a functional, open source PowerPC emulator for the x86 on the internet called PearPC, www.pearpc.net <http://www.pearpc.net/> . I believe it emulates the PowerPC 750 chip. It will run PPC Linux and Mac OS X, and was designed to run a wide variety of PowerPC based operating systems. I have witnessed OS X running on a P4, and it was quite amazing. I realize the PowerPC chip being emulated here is not exactly the same as used in the iSeries, and that the iSeries chips have extended instructions with undocumented IOPs, as pointed out in earlier posts. Nevertheless, I can not help but wonder what changes would need to be made to this emulator to be able to IPL the SLIC. It would be a lot of fun to see it work. It could be that there is insufficient documentation available for the peripherals to actually accomplish a working emulator. Still, I'm curious if anyone is interested in discussing this topic, or actually starting such a project, using a base of code such as PearPC as a starting point.
