No, the CCIV initially had a plain-jane Intel rev 0
82077AA in a 68 pin
PLCC. After Intel "improved" the chip to the 82077AA-1, FM ceased to
work. Fortunately, as I mentioned NSC 8477 is a plug-in replacement,
with the exception of not needing an extra external cap (the pin is NC
on the National chip).
Chuck,
I read through the thread at VCF and see that the 8473 is not drop-in swappable with the
8477. One more question on the 8477 do you know if there is a significant difference
between the 8477AV and the 8477BV revision? Thanks.
