- In addition to that, there are 2 sets of digits on the IC. One of
- them (4 digits) is the date-code and is usually on top. You can tell
- that it is the date-code as it has something like 9123 which translate
- to 1991 workweek 23.
-
- Just look at the other code (which usually have 1 or 2 alphabets) for
- your speed rating.
