what's so special about fitting a 68030RC50 and running it at 40MHz in your board. All versions of the CPU will work (if you change those jumper's).Except that It won't work at 50MHz. You see if you tried that chip in a ACA1220 board then that's a first. I'm going to do that, cos I removed the plastic MC680EC2016, but the dumb ass eBay seller send me the wrong bloody CPU
(I bought the MC68020RC33 but received a MC68060 instead), so all I have is a 68030RC33 to fit (I won't try to overclock it). I know that The firmware in my board is for the MC68020, it just don't have the cache function, and burst mode or MPU , so I won't add any of that in the ACA line. If it works then THAT will be a first, cos Jens has never tried the 68030 with MC68020 firmware (He told me), and as for the microarchitecture, the 68030 is basically a 68020 core with an additional 256 byte data cache and a process shrink and added a burst mode for the caches (Whatever that means), so you see these are just me thoughts, and I have nothing to lose trying it..

I didn´t understood this topic :/
Is this an ACA 1220 Upgraded to Aca 1232 or other thing else?
And on other topics on net i saw that to turn an aca 1220 to an aca 1232 ,it would need not also new socket and processor on place plus the timing freq correct ,but also a firmware upgrade .
Is this true ?
