Does anyone know how to interpret the letters stamped on the side of DEC
module handles? I remember reading that these were FCO and/or Revision
marks, but can't find the reference any more.

I don't have any in front of me, but i think the first number is the
last digit of the year it was made and the next two aro the week of
the year. Most boards weren't made for more than 10 years. The letters
are the cs rev, with "*" being an early release before "A". The etch
rev is etched onto the board, usually after the 50-XXXXX number. There
are exceptions.

Thanks Paul!
That makes sense when I compare chip dates, etc.
