First Amiga 600 FPGA Accelerator

[Darrin]

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.

Holy cow, I thought Minimig used 68000 softcore in a FPGA...

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.
