Cool!
 
Do you have a running prototype?
What kind of speed relative to an original A600 are you aiming for?

Awesome! So did finding those schematics help you then? I still have a folder on my desktop called "for majasta" :D

Good luck with it, I've got an A600 that might be interested.

@AJCopland Yes thank you for the schematics :) I told you i just need something to start :)

@Damiga No prototype yet but all tests are done and all seems to be ok. I ll order prototype in few days.

Ummmm ... I see a video of someone playing with a 3D PCB package, scrolling through the source to the TG68 core and then showing a "schematic" with a cpu socket, some voltage regulators and some pin holes connected

Then I see people congratualting you .... hmmm, yay you!

Cool, glad they helped :)

Don't be put off by problems with the first board(s). I think that regardless of the scale of the project (and yours is rather ambitious!) everyone has had set backs with the first prototypes.

Good luck.

What are you using for a CPU?  A softcore like the FPGA Arcade or a real 68000 turbocharged like on the Minimig?  Nice work.

Minimig has a real MC68000 CPU on it ???

Yes, the Minimig does but the FPGA Arcade doesn't.

However the Minimig allows the 68000 to run at an optional "turbo speed" around 50MHz.

It's the smaller square chip in the corner of the board between the joystick ports and the PIC.

Not enough room on the FPGA, besides using an actual 68000 CPU eliminated a lot of potential bugs especially during early development.  Dennis would have been wondering whether a bug was the fault of the "Amiga" code or the soft CPU.  Besides, 68000 chips are cheap.  :)

So, the leap from FPGA Minimig to an FPGA bases CPU card for a real Amiga isn't huge and if the cost is right then it could make a lot of sense.
