Note:  Dates vary  for when  these  chips were  first available.   Two
databooks have been used one from  '86 the other from '91. Not all the
chips  are  listed  in  the  '86  databook, the  date  of  '87  is  an
assumption.

Note: *2  indicates:   The   UM8253   can   be   replaced   with   the
      UM82C54/-2. The datasheet says it is a superset of the 8253, and
      works up to 10MHz. Also it's compatible with the 8254.  AT: IBM:
