Was I dreaming when I remembered this....

A massive waste of time! I don't know why the MiniMig doesn't just have the 68K signals run to the edge of the board, for an edge connector.

None of the Amiga boards would work as the MiniMig is 3.3Volt and the Amiga is 5Volt... and I was only suggesting providing the 68K signals, not all the other gumpf the Amiga connectors provided. I suppose one could build a proper Edge or CPU conector on the MiniMig, which would bump the Voltage as well as provide the proper signals.

I actually have a CPU connector for MiniMig designed, but finding the right socket/edge design is a pain in the butt.

I know I'm being a pain... but couldn't you add a shifter and then serialise the 68K bus, I'm pretty sure it could be done if the Serial bus ran at a much higher rate than the 7Mhz 68k... that way you'd only need a few pins to connect with... more expensive logic, but simpler connector..

I suppose you could just add jumper wires or posts to add on another board:

You can get connectors from here but I don't know if they have what you want:

I was reading here that you could add posts or copper wires for connectivity:

This site can make plastic housing for the Minimig:

Ok, that would give you a Clockport style header, but with a full 68k Bus... that would seem the most sensible idea... cheap and simple.

Just use this:

"Virtex™-4 FX platform FPGAs provides up to two PowerPC® 405, 32-bit RISC processor cores in a single device."

The softcore MC68020 etc.. + AGA chipset can then be fitted in the logic matrix with room to spare.

No need for connectors, serialisation etc..
Hm, Dual PowerPC.. now that would be a cool "accelerator" :crazy:

Even with only one PPC... there simpy wouldn't be enough room for even the current Minimig... otherwise it would make a good chip to use!
