OK, MC was my abreviation for "Metal Case" by lack of anything better when I 
started the list.

But....

I know someone described all boards once on this list (maybe two years ago). I 
am sure I saved this mail. But I cannot find it anymore :( 
But I would prefer something like C64A above 201470 REV A.

Where the chipcode is not given, I simply don't know or are not sure enough.

This info came from Pasi's list. But he only mentioned the number and the fact 
that it could be found in a SFD-1001. And I don't have one so the rest has to 
be filled in by someone who is so kind to open his SFD-1001 and to give the 
rest of the info.

Correct. Typing error, sorry. I just opened a 1541-II and here I found the 
251828-01.

OK, this one is also on my account.
