Does anyone know what the difference between 486 cache (2 rows of 14 pins) that is marked as *256AK-15 vs. that marked *257AK-15?
I have, for example, cache with markings:
UM61256AK-15
And some as:
W24257AK-15
I am inclined to think that that the *257 contains an extra Kilobit. Any ideas why? Is it for error detection? A parity kilobit? Is the *257 slightly faster and thus intended for use as a the TAG-RAM?
