Hi Trag,

I'm not so sure, that's why I'm asking. These two sure look identical to me

As far as I know the 16.7Mhz is doubled to get the CPU speed (there's a chip near by that does the doubling). It's also consistent with hat I've read on various reputable sites (Mr. Schrier's for example).

Thanks for pointing out that the 64pin socket is for ROMs. It threw me off, since it was so close to the RAM sockets. Now that I think about it, it's not that far off from the SMD ROM chips either.
