I have adapted the minimig Core to the DE2 Board from Terasic with a ALTERA Cyclone 2C35. With an external CPU MC68HC000 runs the Minimig perfekt.

Any idea if Freescale's 68306 would work fairly easily? ( straightaway I can see some work needed to convert IPL2:0 to the 306's separate IRQ lines).

Looks like its built in DRAM controller would make adding upto 64MB pretty easy, plus there's some programmable chip selects and IO pins for extra hackable goodness :hammer:

 MC68306 is a 5Volt I/O part; thus, we would have to use level shifters between 5V MC68306 <=> 3.3V FPGA. Thus, there is not as much benefit in using MC68306 as we would like.
 

Bummer
 I couldn't see anything in the datasheet that specifically said it was a 5v part.( Or rather, I couldn't see a minimum Vcc in the DC specs..maybe I'm blind).

Ta for the reply.
