68xxx Mac - Amiga

[textory]

Lots of Mac questions in this forum... ;-)
I also got one, but its also a bit Amiga related:

Are the Motorola Processors used in Macs and Amigas completely identical or are there big differences?

Could I use, for example, the 68020 of a Mac LC (or the 68030 of a LC II) in my A500 or A2000? Of course, it's not a question of MHz, just in case the cpu dies...

Thx Piru,

I think a 68020 from a LC will work well.

As far as I know the 68LCxx are in the Performas (got two of them, Performa 475 and Performa 630, they are working well). I just thought of keeping the two LCs in my old mac collection as spare parts...

I was thinking about buying an accelerator for my 500/2000 if I can get one from ebay. Running a 68020 in a system where there was a 68000 earlier won't harm the system ... I hope!

@bloodline:

Oooops, sorry ... my clumsy english! I said, that maybe I'd buy an accelerator. I'm sure that this device would never harm an Amiga (maybe it harms me because Wing Commander will be too fast for me). ;-)

@argus:
Disillusioning... thanks a lot for this information. You're right, there's much confusion here. It's not easy to find the specs on the motorola/freescale website (actually I found some in the Google Cache). I think it's the MC68000 (L8 ) used in A500 (and also in A1000, A2000, A500 Plus, CDTV, A600) and the difference to the MC68020 is not only the number of pins (64 -> 114/132).
