The TG68 IP core has full 32-bit address bus so it can access up to 4 GB of memory space.

Mike should finish the new PCB layout in a couple of days and then should have new boards made.

Those games don't use any feature specific to 020+ CPUs. I guess it was easier for developers to have the same code base for different (OCS/AGA) versions of their games.


Holy crap!  Great work there.  I'm so out of touch on how the Minimig core has developed thanks to the way my company has been working me to death lately.

Do you know if "X-Com:  UFO Enemy Unknown AGA" works?

Actually I'm calling AddMemList() function with MEMF_CHIP attribute.


Is there room inside the Minimig v1.x FPGA for your AGA core?  Or the C-One?

In Minimig V1.x FPGA definitely not but it should fit inside C-One Minimig extender FPGA. But be aware that the C-One doesn't support 24-bit video output, has no DDR memory neither dedicated system controller.


Ah, so not much point then.

I'll just have to put my name down for the FPGA Arcade.  :)

Depends how much the daughter cards are. I've got six 100MHz 060 chips here I bought off eBay in a tray for under $40 a few years ago.


Does the tray fit in the Amiga CPU slot or connect to the A1200 trapdoor expansion?

IT could be cool if the case could look like a small A4K


Balls to that, I want it in a full size A2000 case with a couple of house bricks inside to replicate the weight of the original!  :D

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.  

/Mike


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

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.

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? :)


That would be a great way to reuse old cases.  I'm sure I have an old A1200 case somewhere from when I put the mobo in a tower...

Actually I used it to install a Keyrah and it is on a shelf in my room!

There's nothing that makes me love a Minimig more than playing with a real Amiga...

I've just spent my second day trying to get my towered A4000 with a Mediator4000, Deneb, PowerFlyer4000, CF Card Reader, 80GB hard drive, CD ROM, ZIP drive, Indivision, Virge Graphics card and Soundblaster all work in harmony with OS3.9 and all the little programs and drivers you have to install.  I've lost count of how many times I've wiped the hard drive and started the install from scratch again.

I've finally got the Virge card working with a widescreen LCD in 800x600 24 bit mode using P96.  ANything above that is "out of range".  The P96 preferences says it can't find a monitor driver so I can't edit any screen modes apart from what appears in the screen mode prefs...

How long before that Minimig AGA is ready?  :D

The Xilinx's (FPGAs) have just arrived!


Yay!!!  :)

Meanwhile, I've got my A4000 tower looking very nice using the "Classic Workbench" download package (after much mucking about on UAE - thank got for the Deneb card and the fact that I could copy my old OS3.9 to a 8GB memory stick, patch the Classic workbench on UAE, copy it back to the stick and then transfer it to my real Amiga).

Just need to install KG's WHDload games packages now...

Well, I can post a picture of the chip package :)

I certainly won't be soldering 60 of these, the machines will be doing that!

If I can, I'll film the production....

Amigas rolling off an assembly line again...  :D

C'mon man! My A1200's are dying. Quirky keyboards, 030 cards, yellow cases, need a new A1200 class machine to compliment my MiniMIG.


It's just a shame that there's no way to connect an existing A1200 keyboard to this new AGA Minimig as I (and I'm sure others have) an empty shell of an A1200 (containing a Keyrah) that would make a perfect case.

ah yes, I was thinking of the ST keyboard which has the MCU on the keyboard.

There are 30 odd IOs to the Amiga Keyboard, so you would need to wire it up to the main expansion connector if you wanted to do this.
/Mike


So in reality, the only way we could expect to use the A1200 or A600 keyboards is if someone makes a piece of hardware to accept the keyboard ribbon and does all of the work to adapt it to a PS2 connector.

Were "big box" Amiga keyboards just as simple, or would it be easier to produce a PS2 adapter for the A1000/2000/3000/4000 keyboards?
