But what frequency was it designed for? The tech ref shows a 12 Mhz crystal
but some of the test points are marked -16Mhz. Its like the design was for a
faster part but was slowed down later for some unknown reason.

The "Speed up your AT" movement reminds me of all those backyard mechanics
that have been squeezing more performance out the family auto than Detroit
ever thought they were putting in.
