In here you'll find some of the HP part number cross references. There are the best sorted list I could find from the internet. I also put the scan of the microfiches, which has all numbers, even those which don't have a JEDEC number equivalent and had been missing from the published cross-references. Often, but not always, there is enough data to figure out a modern replacement. Often an adequate JEDEC replacement can be found a few lines above or below. The big downside of the fiches is that the parts are not sorted by part number, so it often takes a long time to locate them. Let me know if you successfully OCR them.
