MiniMig with AGA

[yaqube]

Just wondering, how can it be accessing so much memory if it's using a 68000 core? The 68000 only has a 24 bit address bus, which would limit it to 16MB?

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

Nice, when will it be available to purchase?

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

I'm surprised that those programs and games are running on a 68000.  I assumed (I know) that they would have used instructions limited to the 68020 instruction set??  Are there not that many actual differences in the two from the codes perspective?

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.

I want one NOW!!!!  Please tell me when these boards go on sale they'll be under $300 Australian pretty please! (less than 280US?)

as a sidenote here is a link to tobias' own post showing his improved core running with 40mhz on DE2 board hooked as a turbocard to a expansion bus of a 500er.

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?

Yay, this is much more news worthy than X1000 if you ask me!

[Gulliver]

I agree, this is much better than a SAM/X1000

Just call us backward, but I'd like a board, that I can put into a case, that would allow:
 
68000 processor that is speed selectable.
2 meg chip ram (user selectable) 8 meg fast ram
hard drive support
usb keyboard mouse support
usb joystick support
AGA chipset with VGA 60hz output with scan doubler, flicker fixer, etc
that is 99% compatible with Amiga software and is under $300 Australian for the board.
 
If it was available now for that price, I'd buy one.

Love it! Overclocked full 32bit 68000 compatible. Reconfigurable ram. That thing looks friggin fast. Flicker free. Beats the hell outta looking for $250 030 cards (without an FPU)

When this drops I'll be in there like Brazilian swimwear!

[djmartins]

I want one so I can stop searching for a cheap 1200 in the US.
After getting the machine, the card to allow it to run on a monitor, an accelerator,
and ram you have put out some $$$.
A nice NEW card with all the goodies that can run everything would be SWEEEET!

DJ

That is really frakking amazing.  I am thoroughly impressed and amazed.

What really gets me is how snappily it runs.  As for the 020 games, it makes sense to some degree that you would just compile for 68000 and let the 020 do its thing.

This is something I am excited about.  I would be more excited if the A600 HDC is a real, physical interface.  Yeah, you can use flash cards blah blah blah, but a large 2.5" IDE drive (or 1.8", for that matter) would be a nice accessory.  Now, to whore myself out to some more modem installations for the extra moula

This is some seriously nice work.

@Yacube

Well done!

Do I need to design a case for this?

[tasmanian guy]

Seriously this is what Amiga needs.  Legacy hardware that is relatively cheap, but powerful options to bring it up to speed.
 
I'd love a box that can give me what you've demonstrated there!

Absolutely, this beats the shit out of a 10 dollar micro-controller on a 2,000 dollar motherboard. This is something that people can actually use and afford.

The 64 MB of DDR SDRAM is configured as 2 MB Chip, 1.5 MB Slow, 8 MB Fast and 48 MB of extra memory which can be used as additional Chip memory. You can have 50 MB of Chip RAM in total.

I guess that chipmem size modifier works by adjusting mh_Upper and calling FreeMem() for the area to add? (that's how I would do it)

I have to say this is quite nice stuff. Now it just needs the 020 core.
