Problem Title:
PROMs/XC1700:  Ordering ID (part number) and PROM Marking ID are
different for the same part



Problem Description:
Ordering ID's and marking ID's are different for the same PROM device.

PROBLEM:   Ordering ID's and marking ID's are different for the same PROM device
, so the designation you use to order a part will not match
the marking on the actual part.

Marking ID's exist because the complete PROM ordering ID cannot fit on the
small PROM packages and still be readable.   A Marking ID is basically an
abbreviated version of the Ordering ID that is designed to address this problem.




Solution 1:

See page 2-239 of the 1994 Databook for an explanation of the
Ordering ID and Marking ID for PROMs. In the 1996 Databook,
this same information is on p. 6-10.
