HP part numbers for microprocessors and microcontrollers

Information about HP custom numbers, listed below, was compiled from different sources - chip markings, newsgroup and forum postings, auction and sale listings, and others sources. Although we tried to verify every custom part number on the list, some of these numbers came only from one source, and may or may not be correct. Please post a comment if you have correction to one or more part numbers, or if you have information about unlisted HP custom part numbers.
