The 1983 Zilog databook "Ordering Information" section designates speed
grades by letter suffix. No suffix is 4 MHZ, "A" is 6.0 MHz, and "B" is 10
MHz, so a 10 MHz Z8001 in a plastic DIP with a 0-to-70 C temperature range
would be ordered as "Z8001B PS".

However, two things occurred to me:

 1. The parts predate or postdate the databook sufficiently that the
    ordering codes had changed. Are there obvious date codes on the chips?

 2. The parts aren't Zilog issue at all, but rather AMD (a second-source).
    Are there obvious Zilog (stylized "Z") or AMD (up/right-pointing
    arrow) logos on the parts?
