Could you do the same tests that I have made? I mean bustest and sysinfo. I'd like to know how much faster the Blizzard 1220 is.


Vesalia says "Full MC68020 CPU clocked at 16.67 MHz, 20 MHz or 25 MHz"

Is this officially sanctioned or easy now?

If not and I wanted to void my warranty which pins do I need to connect to put it to 25MHz?
