I've got a list of people who have expressed interest.
As soon as the board is up and running and pricing is finalised I'll make an announcement and also mail people on my list to see if they are still interested.

Add me to this list....

@hattig

Toccata emulation may help for that. Anyway I'd like to see 020 support before. And Cirrus||Virge emulation after 020 support :-)


Cirrus and Virge were really tack-on PC parts retrofitted to Amiga. Virge was actually known  in the PC circle as a "3D Video Decelerator" meaning that the 3D rendering performance was slower than simply using the CPU.

I really think the developers would be better off expanding the AGA core to support some "new" chunky 8bit, 16bit or 24bit modes. Here we have the opportunity to go back and fix AGA and make it would it should have been.

The board is equipped with a 24-bit stereo audio DAC. Upgrading Paula to 16 bit and writing suitable AHI driver won't be a big problem. I'm also thinking about more sophisticated solution.

There is still a lot of unused memory bandwidth which can be used for implementation of an advanced flicker-fixer or graphics board (although implementation of CL/S3 chips seems to be impossible).

Both the AHI and P96 require at least 020 CPU and this is the next design object.


Wow. Very cool. If a 16bit Paula is not a big problem, I can't wait to hear about the "more sophisticated solution". Is it a DSP or something?

Is Minimig 1.1 obsolete after this? I'm still trying to get an ARM controller :)

that comment makes me think you have never used RTG on Amiga. On Amiga CirrusGD5446 and Virge work great, infinitely better than AGA. Moreover, P96 drivers already exist for that. When I say Cirrus/Virge I mean making something register compatible so P96/CGX work with it. You could run your Cirrus/Virge at whatever frequency you like since it's not a real chip. BTW, Virge3D part works faster than software rendering with slow cpus. I am not interested on Warp3D on minimig anyway but it would be possible.

I disagree with that because nobody is going to write drivers for that extensions. So zero software would actually use it. In contrast if a gfx chip supported by P96 or CGX was supported we suddenly would be able to run ALL amiga RTG software.


I had CV64/3D in my A2000 and in my 1200T I had a Bvision and later ended up trading that out for a G-REX/Voodoo III.

I disagree that "nobody" would write the extensions for p96. Given that line of thinking, nobody would have written P96 driver for UAE.

I believe in baby steps, minimig then came the arm processor add on.
 
If we can get minimig + AGA + more processing speed (along with being able to use a normal mouse and keyboard, with vga output that acts as a scan doubler) I am happy.
 
Leave all the other stuff for version 2, lets just get the hardware out there!


Interestingly enough, the current minimig 1.1 already runs optionally at A1200 speeds because it clocks the real 68K up to almost 40mhz. Should be interesting to see if the softcore cpu will be faster or slower...

Also should be interesting to see if the soft cpu is more or less compatible.

Who's going to write this driver ? Correct me if I'm wrong, but there's currently no Nvidia driver, and ATI drivers are closed source and PowerPC only (if you exclude Elbox hacks)...


Perhaps look at the UAE Picasso 96 driver. Maybe I'll write it.

Most likely, the P96 driver of UAE goes a long route through the system graphics API rather than poking at the graphics hardware directly, so I'm not so sure that that's a good source.


Still, that driver may be a good example of how to interface with P96.  The hardware side of things will be all new anyway.

@Crom00 - Loriano has the hookup for plastics (because he does it for a living), maybe you two could collaborate or merge designs and base them on mini-itx form factor able to accomodate an internal power supply since MikeJ said the power hookup would be a 4 pin molex to the board... This would also go along with the ATARI ST theme, since it too had an internal power supply...

@MikeJ - Any chance of getting a metal backplane cutout for mini-itx made? This could help the case designers Crom00 and Loriano and lower the cost by one large pane of plastic... or give a whole host of standard mini-itx casing options to the mases that already exist and would only need a cutout metal backplane to be accomodate your board to them... Would seem to be pretty cheap to manufacture at any machine shop where they work with sheet metal.


In that case I suggest Loriano makes a mini A1000 case. I'd like the ability to slide a Solidtek ASK-3100SP mini keyboard under the case. I'm lucky enough to have a PS2 one.

That would be fantastic, thanks.

20-30 Euro for svideo? Yes please, the more connectivity the better IMHO.


I agree Composite and Svideo would be nice...

Full fat video out option here too :)
