Gunnar is looking for coders to showcase this.


Anyone thought about porting this ? :

That might be a nice to do later on, when the FPU is implemented.
Gunnar is looking for coders who can make Apollo-core optimized datatypes using AMMX like jpeg,png, video codecs etc.
Amiga is addictive coz it is fun to use

Hi, does anybody knows do we need extra hardware for A2000, i have "plain one" Ecs , 1Mb chip ram and Kickstart 37.299, ...

Extra hardware to do what? Run this Vampire board?

It occurred to me that if you can provide 68k and "AGA" in an FPGA, wouldn't PowerPC also be possible?

IBM even owns a FPGA implementation of PPC (of course asking for money). Gunnar says it makes no sense because it is too slow.

I figured if a 100MHz 68k was possible, PowerPC wouldn't be too far-fetched.  :D

Just remembered. I recall hearing a while back that the Vampires weren't compatible with Zorro slot expansions. Installing one would render all your other cards inoperable. I wonder if this has been addressed yet?

I've heard of the v500 being used with network cards.

The way the v600 was designed, the bus master signals were used to shut down the old CPU it was clipped onto, so even if you could add Zorro slots to the 600, it couldn't allow them on the bus.

Maybe some early v500 boards had this limitation as well.

Not really. You should keep in mind that the PPC has longer opcodes, and performs less operations per opcode as it is a risk processor. Thus, you first need twice the bandwidth of the 68K to get the same number of instructions into the processor, then you also need *more* instructions to get the same operation(s) done.  Thus, even if you get a FPGA implmentation of a PPC running at 250Mhz, you still don't have quite the power of a 250Mhz equivalent of a 68K. It's more like a 100Mhz 68K, if not even less.

Oh well. Maybe this might be made some day:

It's for big box Amigas, though. I think Gideon is way too busy with the 1541 Ultimate right now though.  :D

This has been mentioned before as well. I think it was something along the lines of "the PPC chip they chose was incompatible with any of the other Amiga PPC hardware or software". Useless. :(  I could be wrong, though! ;)
