The advantage of replicating the WinUAE hardware RTG card is that we have the source code to hand and know how its supposed to work.

The WinUAE Amiga side P96 driver is closed source. Nevertheless the Minimig on the Replay board will have a true-colour RTG board and dedicated P96 driver (yes, I will write it). It won't happen before the 020 compatible CPU core is available (guess why).

The AGA chipset will be enhanced with chunky modes very soon. The chip memory bus access is already contention free but will be improved significantly in the near future.

That sounds just great! Will the built-in chunky modes comply to any existing standard? Graffiti springs to mind.

Yes, the memory organization of chunky display buffer will be linear (as expected). The memory organization of high/true colour modes will be decided during implementation.

BTW Graffiti doesn't use standard display memory organization.

Cool this is what I (and loads of other people) wanted to hear.  

How are coders (like myself) going to support these new chunky modes?   Will it be as easy as a patch to the API (eg writeChunkyPixels) to use the new modes?  In other words, patch the API so that it skips the internal C2P.

You should also have a word with Ratte (the guy behind HighGFX) to see if he can create some new WB screen modes for this sucker.

Wow.  With the release specs plus the proposed updated CPU core and RTG I can see my old "real" Amigas getting sent to a dusty shelf.

The only thing missing is a USB port.  Since purchasing a Deneb for my A4000 I don't think I can live without USB any more.

Yaqube and I are in discussion about the first expansion board, which will contain USB and Ethernet as a minimum.

Excellent!

If you're trying to make me jiz in my pants then you've just managed it!  

On a serious note (honest, I didn't jiz my pants), what would be the odds of getting Chris to port his excellent USB stack to your product and sell it included with the expansion board as he does with Deneb and Subway?

His excellent USB stack is open source.

Really?  I missed that.  Still worth paying for though.

Brilliant stuff, and good to know about the need to access lots of memory.

How's the performance currently?

Is it.  Thought He had just written a version for AROS.  So you could create your own version from the AROS versions.
 
Didnt think he released the whole thing as open source, but I could very well be wrong

I stand corrected.  Thanks for clarifying mongo

BTW - chances are that the replay + expansion board will actually fit inside an A1200 or even A600 case - how about a keyboard controller for the A1200/A600 keyboards?
