Found this video about a minimig with a real 060 clocked @ 106 mhz.

Is a real product?

That is running on a FPGAArcade Replay board I believe...
Minimig AGA core.

Interesting that the 060 is clocked @ 106 mhz.

Can't wait to see Acube minimig 2

This is Yaqube's FPGAArcade Replay expansion 68060 board plugged into the FPGAArcade Replay. The 68060 is a rev 6 68060 which can be overclocked to about 100MHz but they are in limited supply. The chipset core started as the MiniMig core but it is highly customized and much enhanced including AGA support. This is not the MiniMig 2/plus from Acube that will have the Dragonball "68000" CPU. The product is real but nothing is "officially" for sale yet.

@matthey

68040s are these real or a joke ?

68020 compatible

@matthey

The 68000 processor used by acube seems to be faster than the original 68000.

Just a quick question to the experts: a coldfire could be not feasible?

Take a look at this :

Xilinx takes Zynq-7000 All Programmable SoC to 1 GHz

http://www.eetimes.com/document.asp?doc_id=1317401


Zynq-7000 -> Digikey part XC7Z010-1CLG225C
PRICE £54.86

http://www.digikey.com/product-search/en?mpart=XC7Z010-1CLG225C&vendor=122

either use Fast FPGA to run 68000 code

or use arm cortex processors to emulate 68000 using cyclone

http://notaz.gp2x.de/cyclone.php

a mali chip would be ideal as it has fast GFX eg

MediaTek MT8127 SoC

http://simplytech.in/mediatek-mt8127-quad-core-processor-mali-450-mp4-gpu-launched-tablets/

If only 68000 compatible hardware like this was available for us.

I love to investigate where the original arm cortex was fabricated and at what cost, so we can do the same !

@asymetrix

I think that coldfire would be more interesting, just to avoid emulation via arm.

As far as I know is Coldfire no alternative because not compatible to 68000. The rest would have to be emulated and that would destroy all performance gains.

@OlafS25

I see. Reading the docs Coldfire is not 100% compatible

Old stock of the 68040 is available today for less cost than the 68060. The old MC68302, MC68340 and MC68360 "communication controllers" could interface with a 68040. They had a CPU32 processor internally and SoC capabilities that are dated today for most applications. This Microsemi 68332 looks very similar to the MC683xx chips. The 68040 makes much less sense today as there are much more energy efficient solutions for 68k performance. Innovasic's Fido is a more modern and useful 66MHz CPU32 processor with SoC features. It's specialized for industrial and embedded control and communications but can be used for other purposes. Supervisor mode and interrupt handling are much different than the 68k but it has fast interrupt handling and context switches (1 cycle in most cases) that would be useful for emulation of 68020 instructions and addressing modes. The CPU32 instruction set and addressing modes are closer to the 68020 than the latest ColdFire. A CPU32 would be very compatible with 68000 code which the ColdFire is not. The best solution for 68020 compatibility, configurability, performance, energy efficiency and cost is an fpga processor. I believe it is possible to have better than 68060 performance from a $30 U.S. fpga and the value of fpgas steadily improves.
