Hi Sheepz, is it specifically a 060 CPU you want or something to make your A2000 faster?
There are a couple of recent options if it doesn't have to be an 060. As well as the Apollo Firebird you can also get the PiStorm: It replaces the 68000 CPU with an adapter and a Raspberry Pi 3 which then runs software to emulate a fast 68030. (loads of results if you Google it)
